Unit 7- Energy

Front

What happens to potential energy as a skier moves down a slope?

Back

Potential energy decreases.

Front

What type of energy is primarily present when a roller coaster is at the top of a hill?

Back

Potential energy.

Front

What type of energy transformation occurs when a toy car is pushed up a ramp and then released?

Back

Kinetic to potential, then potential to kinetic.

Front

How can you demonstrate the conversion of potential energy to kinetic energy using a simple pendulum?

Back

By measuring the height and speed of the pendulum at different points.

Front

What happens to a ball's energy when it is thrown into the air and then caught?

Back

The ball gains potential energy as it rises and gains kinetic energy as it falls.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

Give an example of energy transformation in a pendulum.

Back

As the pendulum swings, it transforms potential energy at its highest point to kinetic energy at its lowest point.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
