What is Kinetic Energy?

Back

Kinetic Energy is the energy that an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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 gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

At which point is Kinetic Energy highest in a pendulum swing?

Back

Kinetic Energy is highest at the lowest point of the swing, where the speed of the pendulum is greatest.

Front

At which point is Potential Energy highest in a pendulum swing?

Back

Potential Energy is highest at the highest points of the swing, where the pendulum is momentarily at rest.

Front

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

Back

In a closed system, the total mechanical energy (the sum of Kinetic and Potential Energy) remains constant, assuming no energy is lost to friction or air resistance.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy is directly proportional to mass; as mass increases, Kinetic Energy increases if velocity remains constant.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic Energy is proportional to the square of velocity; if velocity doubles, Kinetic Energy increases by a factor of four.

Front

What happens to Kinetic Energy as an object rises in height?

Back

As an object rises in height, its Kinetic Energy decreases while its Potential Energy increases, conserving total mechanical energy.

Front

What is the formula for calculating Potential Energy?

Back

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

Front

What is the point of equilibrium in a pendulum?

Back

The point of equilibrium in a pendulum is the lowest point in its swing, where Kinetic Energy is maximized and Potential Energy is minimized.
