Kinetic and Potential Energy

What is kinetic energy?

• Energy stored in an object due to its position

• Energy an object has due to its motion

• Energy an object has due to its chemical composition

• Energy that disappears when an object moves

Which of the following factors affects kinetic energy the most?

• Shape and temperature of the object

• Speed and mass of the object

• Color and texture of the object

• Height and surface area of the object

Which of the following is an example of potential energy?

• A car moving on the highway

• A ball rolling down a hill

• A swimmer diving into a pool

• A stretched rubber band before release

Gravitational potential energy depends on which two factors?

• Mass and height above the ground

• Mass and velocity

• Speed and direction

• Shape and density

What happens to an object’s kinetic energy if its speed doubles?

• It stays the same

• It doubles

• It quadruples

• It decreases by half

Which of the following best explains elastic potential energy?

• Energy stored due to an object’s height above the ground

• Energy stored due to an object’s shape being stretched or compressed

• Energy stored in food and fuel

• Energy an object has while in motion

Which of the following best describes the energy transformation of a pendulum?

• Potential energy transforms into kinetic energy and back

• Kinetic energy transforms into sound energy

• Kinetic energy transforms into thermal energy

• Potential energy disappears completely when the pendulum moves

When a biker moves up a hill, what happens to their kinetic and potential energy?

• Kinetic energy increases while potential energy stays the same

• Both kinetic and potential energy decrease

• Both kinetic and potential energy increase

• Kinetic energy decreases while potential energy increases

Which statement is true about the relationship between kinetic and potential energy?

• An object can have both kinetic and potential energy at the same time

• Kinetic and potential energy are unrelated

• An object loses all its kinetic energy before gaining potential energy

• Kinetic energy can exist without mass

Why does a stretched rubber band have potential energy?

• Because it is in motion

• Because it has mass

• Because it is compressed or stretched and can return to its original shape

• Because it is heated
