So ping pong balls are hollow, which means the gas inside you spread out where there's not that many particles. Golf balls are much much denser and there's going to be many more particles, Many more atoms in here, which is going to be equal to more mass.
What is the mass of a golf ball compared to ping pong?
Say a golf ball has a mass of 0.046kg. Say a ping pong ball has a mass of 0.0027kg. As pointed out arm speed between throwing a golf ball and ping pong ball will be about the same. Release speed will be about the same, so the main difference is aerodynamic drag. Note that k is proprotional to 1/m so the smaller the mass, the larger k.
Why can't I throw a ping pong ball as fast as golf?
The velocity of the heavier projectile, however, is still 96% of its original value. So it only seems like you're not throwing it as fast because the ping pong ball carries no "oomph" with it. That's why you play with golf balls outside and ping pong balls inside.
Why does a dimpled ping pong ball go farther than a smooth?
So a smooth golf ball would still go a lot further than a ping pong ball, and a dimpled ping pong ball would still go far less distance than a smooth golf ball. A MAJOR reason not mentioned so far is the importance of surface geometry for the total (normal) drag upon the ball.
Why do golf balls slow down with size?
That means that the air is exerting the same decelerating force on balls of equal size. But the more massive golf ball slows down less, because it's more massive. The identical decelerating forces on the balls is going to produce a smaller deceleration for the more massive ball.
What are the changes that at least one of the atoms exhaled by your very first breath will be in your next breath?
what are the chances that at least one of the atoms exhaled by your very first breath will be in your next breath? hydrogen and oxygen always react in a 1:8 ratio by mass to form water. early investigators thought this meant that oxygen was 8 times more massive than hydrogen.
In what sense can you truthfully say that you are a part of every person around you quizlet?
In what sense can you truthfully say that you are a part of every person around you? We are continually exchanging out atoms. Which contributes more to an atom's mass: electrons or protons?
What atoms make up newborn babies?
Where were the atoms that make up a newborn infant "manufactured"? Atoms were "manufactured" in the stars that exploded in the origin of the universe, before the Sun and Earth came into existence.
Why dont all collisions between reactant molecules lead to product formation?
Solution. All collisions of reactant molecules do not lead to a chemical reaction because the colliding molecules need to possess certain energy which is greater than the activation energy Ea and proper orientation.
Why is it impossible to walk through a wall?
This is called the Pauli Exclusion Principle, and it applies to all fermions. It also means that atoms are pretty effective at blocking other atoms from getting all up in their space. This is what makes solid objects solid, and keeps them from passing through each other.
Does it make sense to say that table about 99.9% empty space?
Yes. A textbook like all material things is made up of atoms, which are considered to be 99.9 percent empty space.
What is the difference between atom and element?
An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.
How many types of atoms can you find a pure sample of any element?
How many types of atoms can you expect to find in a pure sample of any element? A pure sample of any element is only one kind of atom.
How does a molecule differ from an atom?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.
How collision theory helps you understand about chemical reaction?
Collision theory states that for a chemical reaction to occur, the reacting particles must collide with one another. The rate of the reaction depends on the frequency of collisions. The theory also tells us that reacting particles often collide without reacting.
What factors determine whether a collision between two molecules will lead to a chemical reaction?
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
How does collision theory affect the chemical reaction?
Collision theory states that the rate of a chemical reaction is proportional to the number of collisions between reactant molecules. The more often reactant molecules collide, the more often they react with one another, and the faster the reaction rate.
