Potential Vs. Kinetic Energy

What is the energy associated with motion called?

• Kinetic

• Kinestetic

• Potential

• Force

What two factors could you change for an object to increase its kinetic energy?

• Mass and Weight

• Mass and Energy

• Velocity and Speed

• Mass and Velocity

How can you increase the kinetic energy of an object?

• decrease the mass of an object to increase kinetic energy

• keep the mass of an object the same to increase kinetic energy

• increase the mass of an object to increase kinetic energy

True or False: increase velocity to increase the kinetic energy

• True

• False

How is potential energy different from kinetic energy?

• potential and kinetic energy are stored energy

• potential energy is moving; kinetic energy is anything that is in place

• potential energy is stored; kinetic energy is anything moving

• potential energy uses force; kinetic energy uses velocity

The TOTAL energy of an object (both the kinetic/motion AND potential/position energy an object contains)

• Kinetic energy

• Potential Energy

• Mechanical Energy

• Chemical Energy

The drawing shows a wind-up toy. The key is wound or turned, compressing a spring inside the toy.

When it is released, the toy will move. When would the wind-up toy have the greatest elastic potential energy?

• Winding compresses the spring, directly after the toy is wound, it will have the greatest elastic potential energy.

• Winding compresses the spring, directly before the toy is wound, it will have the greatest elastic potential energy.

• Winding compresses the spring, wait for the toy to stop winding and then wind the toy again, it will have the greatest elastic potential energy.

Which is an example of elastic potential energy being used? (check all that apply)

• Kids jumping on a trampoline.

• A metal chain around a locked gate.

• A bungee cord holding the trunk shut of a car

• The hair band keeping together

which point has the most potential energy

• G
• f
• b
• a
