What is the kinetic energy of a 45g golf ball?
The kinetic energy of a 45 gram golf ball traveling at 20 m/s is 9 Joules . Kinetic energy=? We define kinetic energy as the energy gained by a body by virtue of its motion or from its state of rest to its motion.It’s unit is Joules. 1000 grams = 1 kilogram. Kinetic Energy= 9 Joules .
How do you find the kinetic energy of a ball?
To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.
How do you calculate kinetic energy from km/h to joules?
To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules.

Kinetic Energy
Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.
Using the kinetic energy calculator
This kinetic energy calculator is useful for estimating the energy a body acquires through movement of any kind. For example, it can be used to calculate the kinetic energy of a person, vehicle (car, truck, train), plane, football, as well as for falling bodies that crash into the ground.
