The unit for energy and work is

• J

• N

• m/s

• m/s/s

A 5 kg ball is lifted 12 m above the ground. It's gravitational potential energy is

• 60 J
• 600 J
• 17 J
• 2.4 J

The law of conservation states that

• every action has an equal and opposite reaction
• all matter has thermal energy
• energy cannot be created or destroyed, only changes form
• heat moves from an object of higher temperature to an object of lower temperature
