4 - Energy, Work, & Power | Energy Skate Park

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object above the ground.

Front

What is kinetic energy?

Back

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

Front

At what point does a skateboarder have the least potential energy on a ramp?

Back

At the lowest point of the ramp.

Front

At what point does a skateboarder have the greatest kinetic energy on a ramp?

Back

At the lowest point of the ramp, just before ascending.

Front

What happens to potential energy as a skateboarder descends a ramp?

Back

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

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does friction affect the energy of a skateboarder on a ramp?

Back

Friction converts some mechanical energy into thermal energy, reducing the total mechanical energy available for motion.

Front

What is the maximum height a skateboarder can reach after descending a ramp?

Back

The maximum height is equal to the initial height from which the skateboarder descended, assuming no energy is lost to friction.

Front

What is the relationship between height and potential energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.
