Work Power and Energy Mixed Practice

The ability to do work

• Power

• Force

• Energy

• Motion

Combines all of the kinetic and potential energy in a system

• Mechanical Energy

• Mechanical Advantage

• Power

• Work

This requires a force that causes motion

• Work

• Energy

• Inertia

• Gravity

Mark the two things that affect gravitational potential energy

• Mass

• Weight

• Height (distance)

• Power

If a piece of wood contains 500 joules of chemical potential energy, how many joules of light and thermal energy can it produce when it is burned?

• 100 joules

• 500 joules

• 1000 joules

• 0 joules

The rate of work or how fast work gets done

• Power

• Force

• Energy

• Inertia

The faster an object moves, the ________ kinetic energy it has. 

• more
• less
• none of the above
• all of the above 

What two factors affect an object's kinetic energy?

• area and volume

• mass and weight

• weight and height

• mass and speed

Increasing an object's mass will increase its kinetic energy.

• true

• false

Increasing an object's speed will increase its kinetic energy.

• false

• true
