Organize these pictures into the right categories

Groups:

(a) Potential Energy

,

(b) Kinetic Energy

• 
• 
• 
• 
• 
• 
• 

If you want to decrease the kinetic energy, you can

• decrease the mass

• decrease potential energy

• decrease the speed

• All of the choices help to decrease kinetic energy
