Energy and Energy Transformations

What is energy?

• the ability to cause change

• the ability to undo change

• what you get when you drink an energy drink

• the ability to increase the temperature of an object.

The energy of motion

• Chemical Energy

• Potential Energy

• Kinetic Energy

• Thermal Energy

An object's kinetic energy depends on the object's

Objects can still have energy even if they aren't moving

• True

• False

Stored energy due to the interactions between particles or objects.

Which of the following is not a type of Potential Energy?

• Elastic

• Gravitational

• Chemical

• Thermal

The transfer of energy that occurs when a force makes an object move in the direction of the force while the force is acting on the object.

• potential energy

• work

• kinetic energy

• force

Energy transformation is an efficient process

• True

• False

When you throw a ball, at it's highest point in the air, the gravitational potential energy is the

• lowest

• the ball does not have gravitational potential energy

• highest

• average of the potential and kinetic energies.

When you throw a ball, at the highest point in the air, the ball's kinetic energy is

• the lowest

• the highest

• the ball does not have kinetic energy

• the average between the gravitational PE and PE
