Lesson: Kinetic Energy

In this lesson, we will learn how to calculate the kinetic energy of objects of different masses, moving at different velocities.

Sample Question Videos

Q1:

An object that has 9 J of kinetic energy is moving at 3 m/s. What is the mass of the object?

Q2:

An object with a mass of 1.25 kg has a velocity of 12 m/s. What is the object’s kinetic energy?

Q3:

An object’s kinetic energy when it moves at different velocities is shown in the table. What is the object’s mass in grams?

Velocity (m/s)	1	2	3	4	5
Kinetic Energy (J)	0.1	0.4	0.9	1.6	2.5
