Potential and Kinetic Energy

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and speed.

Front

At which point in a swing is potential energy greatest?

Back

At the highest point of the swing.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is speed.

Front

What is the principle of conservation of energy?

Back

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

Front

What are the two factors that affect kinetic energy?

Back

Mass and speed.

Front

Give an example of energy transformation from potential energy to kinetic energy.

Back

A swing swaying back and forth.

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 type of energy is associated with the height of an object?

Back

Gravitational potential energy.

Front

How does mass affect kinetic energy?

Back

Increasing the mass of an object increases its kinetic energy if speed remains constant.
