Potential and Kinetic Energy Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

Where is potential energy the greatest when tossing a ball?

Back

At the highest point of its trajectory.

Front

What happens to potential energy as a roller coaster goes downhill?

Back

Potential energy is converted into kinetic energy.

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created nor destroyed; it can only be transformed from one form to another.

Front

How does the energy of a skateboarder change as they go down a ramp?

Back

As the skateboarder descends, potential energy decreases while kinetic energy increases.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 0.5 × mass (m) × velocity (v)².

Front

In a closed system, what happens to the total energy?

Back

The total energy remains constant; it is conserved.
