Potential/Kinetic Energy

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, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating work done?

Back

Work done (W) is calculated using the formula W = F × d, where F is the force applied and d is the distance moved in the direction of the force.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate the kinetic energy of an object?

Back

Kinetic Energy (KE) is calculated using the formula KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

Where is potential energy highest in a tossed baseball?

Back

Potential energy is highest at the peak of its toss, where the baseball is at its maximum height.

Front

Where is kinetic energy highest in a tossed baseball?

Back

Kinetic energy is highest just before the baseball hits the ground, where its speed is greatest.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What is the relationship between potential and kinetic energy?

Back

Potential and kinetic energy are forms of mechanical energy; they can convert into each other, but the total mechanical energy remains constant in a closed system.
