. Usually scientists and engineers look at the kinetic energy of things in motion. (ex. a plane, a running football player, air molecules in a room, a particle in a particle accelerator.)

. You might want to measure potential energy for something that has the ability to do work but isn’t currently doing work. (ex. a battery, a burger, a bowling ball at the top of a hill, a stretched rubber band)

In physics, there are different “kinds” of potential energy. In reality they are all the same concept but depending on the situation the amount of potential energy may depend on different things. 

What affects potential and kinetic energy?

1. What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s? 

2. An object has a kinetic energy of 25 J and a mass of 34 kg , how fast is the object moving? 

3. An object moving with a speed of 35 m/s and has a kinetic energy of 1500 J, what is the mass of the object?

4. What is the Kinetic Energy of a 1200 kg object that is moving with a speed of 24 m/s?

5. An object has a kinetic energy of 14 J and a mass of 17 kg , how fast is the object moving?

6. An object moving with a speed of 67 m/s and has a kinetic energy of 500 J, what is the mass of the object?

7. What is the Kinetic Energy of a 478 kg object that is moving with a speed of 15 m/s?

8. An object has a kinetic energy of 88 J and a mass of 45 kg , how fast is the object moving?

9. An object moving with a speed of 21 m/s and has a kinetic energy of 140 J, what is the mass of the object?

10. What is the Kinetic Energy of a 100 kg object that is moving with a speed of 12.5 m/s?
