Potential and Kinetic energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a ball held at a height has potential energy because of its position above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

How does height affect potential energy?

Back

Potential energy increases with height. The higher an object is, the more potential energy it has due to gravity.

Front

What factors affect potential energy?

Back

Potential energy is affected by the object's mass and its height above the ground.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy. For example, when a ball is dropped, its potential energy decreases while its kinetic energy increases.

Front

What is the law of conservation of energy?

Back

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

Front

What is the unit for mass?

Back

The unit for mass is the kilogram (kg).

Front

What is the unit for speed?

Back

The unit for speed is meters per second (m/s).
