Conservation of Energy

Front

What happens to the potential energy of a rock as it falls off the side of a cliff?

Back

The potential energy decreases as the kinetic energy increases.

Front

At which point does a ball have the greatest potential energy?

Back

At the highest point (Point C).

Front

What is the Potential Energy at the TOP (highest point)?

Back

25 J.

Front

At which point is kinetic energy highest in a swinging pendulum?

Back

At the lowest point (Point 3).

Front

What is the unit of measurement for kinetic energy?

Back

Joules.

Front

Define potential energy.

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

State the law of conservation of energy.

Back

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

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
