and ​

Select answer

energy.

Multiple Choice

Which of the following statements about kinetic energy is correct?

• Kinetic energy increases as the speed of an object increases.

• Kinetic energy decreases as the mass of an object increases.

• Only living things can have kinetic energy.

• Kinetic energy is not related to motion.

Multiple Choice

Which of the following best describes kinetic energy?

• Energy stored due to position

• Energy of motion

• Energy released during a chemical reaction

• Energy from the sun

Potential and Kinetic Energy transform into one another due to the position of the moving object.

The rollercoaster car has 100% Potential energy at the tip of the hill and as the car coasts down the hill the energy transforms into Kinetic Energy.

The bottom of the hill has the highest Kinetic Energy.

Multiple Choice

A 3 kg baseball and a 1 kg wiffle ball are both moving at 30 m/s. Which has more kinetic energy and why?

• The baseball, because it has more mass.

• The wiffle ball, because it is lighter.

• Both have the same kinetic energy because their velocities are equal.

• Neither, because kinetic energy does not depend on mass.
