What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically measured relative to a reference point.

How does the position of an object affect its gravitational potential energy?

Back

The gravitational potential energy increases with height; the higher the object is positioned in a gravitational field, the greater its potential energy.

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is kinetic energy?

Back

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

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

How is mechanical energy converted to electrical energy?

Back

Mechanical energy can be converted to electrical energy through devices like generators, which use motion to produce electricity.

Front

What type of energy does a battery store?

Back

A battery stores chemical energy, which can be converted into electrical energy when needed.

Front

What is the relationship between potential energy and kinetic energy in a closed system?

Back

In a closed system, the total mechanical energy (potential + kinetic) remains constant, meaning potential energy can convert to kinetic energy and vice versa.

What factors affect the gravitational potential energy of an object?

Back

The gravitational potential energy of an object is affected by its mass, the height above a reference point, and the strength of the gravitational field.

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
