Energy cannot be created or destroyed, only converted from one form to another

• true
• false

Answer explanation

You saw this in the pHet Lab. The "lost" energy was converted to useless heat. It wasn't gone. We just couldn't use it to keep moving.

If these are all moving at the same speed, the vehicle with the greatest KE would be

(Think about their masses)

• 
• 
• 
• 

Answer explanation

Kinetic energy not only involves motion, it involves mass. The more mass, the more Kinetic Energy for the same speed.
