According to Rule 5-3, if a ball breaks into pieces as a result of the stroke, the stroke is cancelled and the golfer plays again, without penalty, from the original spot. A ball that’s unfit for play (visibly cut, cracked or “out-of-round”) may be substituted mid-hole.
What happens if you hit the golf ball more than once?
Golf's New Rules: Major Changes 2019 Rule: Under Rule 10.1a, if the player’s club accidentally hits the ball more than once during a single stroke: There will be no penalty and the ball will be played as it lies.
What happens if you hit someone's golf ball on the Green?
There will be no penalty incurred, and in match play, also no penalty. If you putt your ball, and it strikes a competitors ball (which is also on the green) you will incur a 2 shot penalty (stroke play only). Your ball will be played from where it lies, and your friend's ball returned to its original resting position.
What are the rules for hitting the ball in golf?
Golf Rule 14, Striking The Ball. 14-4. If the club hits the ball more than once during a swing, the shot counts and a penalty stroke is added. If the ball strikes another object (a tree), ricochets and hits the clubhead, no penalty is incurred. 14-5. The golfer is not allowed to hit a moving ball.
Is it illegal to hit a moving ball in golf?
The golfer is not allowed to hit a moving ball. A player may hit a ball that’s oscillating (being blown by wind, for instance) without penalty. Exception: If the ball moves after the player starts swinging, there’s no penalty provided the player, caddie or partner didn’t intentionally cause it to move. 14-6.
When a golf club hits a golf ball the change in momentum of the ball is blank the change in momentum of the club?
When a golf club hits a golf ball, the change in momentum of the ball is smaller than the change in momentum of the club. False, because the change in momentum of the ball is much greater because it was at rest. It went from zero momentum to a lot (however much the mass is times the velocity given to it by the club).
What is the change in the golf balls momentum?
We are told that this moving golf ball hits the golf club and comes to rest. This means that the golf ball's velocity changes from this initial value of 20 centimeters per second to a final value of zero centimeters per second.
What forces act on a golf ball when it is hit?
Some of these forces include: gravity, aerodynamic drag, and aerodynamic lift. Each force acts independently on the moving golf ball. For a greater distance to be achieved, one needs to increase the acceleration of the ball by increasing the force with which the ball is struck or swinging the club faster.
When a golf club hits a golf ball what is transferred from the club to the ball?
When a golf club is swung and hits a stationary golf ball, some of the club's kinetic energy transfers to the ball as the club does “work” on the ball. In an energy transfer such as this one, energy moves from one object to another, but stays in the same form.
What is true about impulse and momentum?
Impulse is a quantity which depends upon both force and time to change the momentum of an object. Impulse is a force acting over time. b. TRUE - Impulse is a vector quantity Like momentum, impulse is not fully described unless a direction is associated with it.
Why the momentum of a billiard ball rolling on a billiard table changes?
If a billiards ball is rolling around on the table, it has momentum. When the balls strike each other or the table walls, their velocity will change. A change in velocity can be from a change in speed, a change in direction, or both. If the ball's velocity changes, so does its momentum.
What forces are used in golf?
Two types of forces are important to the golf swing: normal forces and shear forces. Normal forces are illustrated in the linear components of the swing, and shear forces are illustrated in the rotational components of the swing. Normal forces are applied by the feet downward or perpendicular to the ground.

What evidence is there that energy is transferred as a golf club does work on a golf ball?
What evidence is there that energy is transferred as a golf club does work on a golf ball? The kinetic energy of the golf ball suddenly increases as the club strikes it.
How is work transferred?
Work is the transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If you put energy into an object, then you do work on that object (mass). If a first object is the agent that gives energy to a second object, then the first object does work on the second object.
What are the new rules for golf?
2019 Rule: Under Rule 10.1a, if the player’s club accidentally hits the ball more than once during a single stroke: There will be no penalty and the ball will be played as it lies.
Why is double hit not a penalty?
Reasons for Change: Where a double hit occurs as part of a single stroke and was not the intention of the player, it was felt unfair and unnecessary for the player to be penalized. Just as there is no penalty if a player’s ball accidentally deflects off his or her body, equipment or caddie, there is no need for a penalty when a player accidentally ...
What does it mean when a golf ball begins its journey through the air?
As it begins it’s journey through the air towards their target or the out of bounds fence (that depends on the golfer of course).
How does a golf ball flatten in slow motion?
It shows you in slow motion just how much the golf ball is compressed and flattened by the force of the impact of the club head regardless of how much speed its hit with.
What handles the high speed impact of the club head?
Secondly, the ball’s compression handles the high speed impact of the club head.
Is a golf ball hard?
Most golfers, especially those that have ever been hit by a golf ball will tell you that a golf ball is pretty hard.
Does the side of the golf ball flatten?
At impact as the golf ball reacts to the energy that the club head imparts to it, not only does the side of the golf ball that was hit flatten as you would expect but all that energy transfers through the whole golf ball deforming it sufficiently that just before it flies away it is actually longer than normal and not particularly round either!
Why is golf changing?
Reasons for Change: Many objects, persons and animals are present on a golf course during play; it is inevitable that a ball in motion will sometimes hit them before coming to rest, and a player is generally required to accept the outcome (whether good or bad). Just as there is no penalty in stroke play if one player ...
What are the new rules in golf?
Golf's New Rules: Major Changes. New Rule: Under Rule 11.1, for all accidental deflections, including when the ball hits the player or opponent or their equipment or caddies: There is no penalty and the ball is played as it lies (with limited exceptions). To address any concern that a player might deliberately position equipment to act as ...
Do you have to pay a penalty for a deflected ball in stroke play?
Just as there is no penalty in stroke play if one player (or his or her equipment or caddie) accidentally deflects another player’s ball, there is no need for a penalty when a player (or the player’s equipment or caddie) accidentally deflects his or her own ball.
What is the rule for golf balls being lifted or moved by outside influence?
This is covered in Rule 9.6, Ball Lifted or Moved By Outside Influence. (Note: Another player's golf ball is included in the definition of "outside influence.") There is no penalty to either player as long as this procedure is followed:
What happens if you hit both golf balls on the green?
If both balls were on the green, the golfer whose ball was in motion is penalized. If neither ball, or only one golf ball, was on the green, there is no penalty to either golfer. In both scenarios, the golfer whose ball was in motion at the time of the collision must play her ball from where it comes to rest.
What is scenario 1 in golf?
Scenario 1: Neither Ball, or Just One Ball, on the Green. This could mean the shot in question was a tee shot, or an approach played into a green, or any other scenario other than when both balls were on the green prior to making the stroke. For example, your fellow-competitor hits a tee shot, then you hit yours, ...
Who plays the ball as it lies?
The golfer whose shot struck the ball at rest plays his ball as it lies; the person whose ball was moved returns the ball to its original position.
Is there a penalty for hitting a golf ball in match play?
In match play, there is no penalty. In stroke play, it's a 2-stroke penalty to the player whose ball was in motion when the balls collided. Repeat: It's not a penalty against the golfer whose ball was at rest when it was hit; the penalty is against the golfer whose ball was in motion when the collision happened.
What happens if you don't replace the ball in a match?
NOTE: Failure to replace the ball that was moved to its original spot; or moving the ball that did the striking (rather than playing it as it lies) results in loss of hole in match play or a 2-stroke penalty in stroke play . If you aren't certain where the ball at rest was before it was knocked away by the colliding ball, use your best judgment to return it to a spot nearest where it most likely was.
What happens if you hit a ball on the fairway?
On the Fairway. If your ball strikes a fellow players ball on the fairway by accident, both players will play from where their balls lie. There will be no penalty incurred. Playing onto the green.
Do you get a penalty for hitting a competitor's ball on the green?
There will be no penalty incurred, and in match play, also no penalty. On the Green. If you putt your ball, and it strikes a competitors ball (which is also on the green) you will incur a 2 shot penalty (stroke play only). Your ball will be played from where it lies, and your friend's ball returned to its original resting position.
Where do you drop a golf ball?
You’ll drop if the ball is off the green, or place it on the “estimated spot right under where the ball first came to rest on the person, animal or moving outside influence” when the ball is on the putting surface.
Where was Player 1 in the golf game?
Player 1 was on the wide right of the 15th fairway, approximately 110 yards from the green. Player 2 was on the left of the fairway approximately 120 yards from the green. “Both played almost simultaneously and the balls very nearly collided in mid air as their flight paths crossed.
Does the stroke count as a ball replacement?
This one’s actually a bit more likely. In this case, the stroke doesn’t count and the ball must be replaced on its original spot. If you’ve forgotten where that was, estimate as best you can.
Have a question for our Rules of Golf expert?
Despite the simplification of the Rules of Golf at the beginning of 2019, there are still some that leave us scratching our heads. And as I’ve passed the R&A’s level 2 rules exam with distinction, I am more than happy to help.
