Kinetic Energy is defined as the work needed to accelerate a body of a given mass from rest to its current velocity.
Ek = Kinetic Energy, M = Mass of object, V = Velocity or Speed of object,
Determine the Kinetic energy of a 500kg roller coaster train which moves at a speed of 20 m/s. M = 500 kg, V = 20 m/s
Substitute the values in the below kinectic energy formula:
=½ x 500 x 202 = 0.5 x 500 x 400 Kinetic Energy: Ek = 100000 Joules or 1 x 105 Joules This example will guide you to calculate the kinetic energy manually.
What is the speed of a 55 kg woman running with a kinetic energy of 412.7 J? Ek = 412.7, M = 55 kg
Substitute the values in the below Velocity formula:
This example will guide you to calculate the velocity manually.
This tutorial will help you dynamically to find the Kinetic Energy problems.
