Potential vs Kinetic 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 square of its speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is speed.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on two factors: mass and speed of the object.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total energy constant.

Front

What type of potential energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy.

Front

What type of energy is stored in food?

Back

Food contains potential energy, which can be converted into kinetic energy when consumed.

Front

If an object is at rest, what type of energy does it have?

Back

An object at rest has potential energy, but no kinetic energy.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.
