Kinetic and Potential energy

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.

At which point is potential energy greatest in a roller coaster ride?

Back

At the highest point of the ride.

Front

At which point is kinetic energy greatest in a roller coaster ride?

Back

At the lowest point of the ride.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) * gravity (g) * height (h).

Front

How does height affect Potential Energy?

Back

The higher an object is, the greater its potential energy due to the increased height in the potential energy formula.

Front

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

Back

In a closed system, the total mechanical energy (Kinetic + Potential) remains constant, meaning energy can transform from one form to another but is not lost.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a running athlete, or a flowing river are all examples of kinetic energy.
