Kinetic and Potential Energy Practice

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Potential Energy?

Back

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

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has. Kinetic energy increases with the square of the speed.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

At what point does a roller coaster have the highest Potential Energy?

Back

A roller coaster has the highest potential energy at the top of a hill.

Front

At what point does a roller coaster have the highest Kinetic Energy?

Back

A roller coaster has the highest kinetic energy at the lowest point of the track.

Front

What is the relationship between Kinetic Energy and Potential Energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, assuming no external forces do work.

Front

What is an example of converting Potential Energy to Kinetic Energy?

Back

An example is a ball dropped from a height; as it falls, its potential energy converts to kinetic energy.
