Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height 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 thermal energy?

Back

Thermal energy is the internal energy of an object due to the kinetic energy of its molecules, often associated with temperature.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting kinetic energy to thermal energy through friction.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = 1/2 mv².

Front

What happens to gravitational potential energy as an object is raised higher?

Back

As an object is raised higher, its gravitational potential energy increases due to the increase in height.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car or a person running.

Front

At which point does a swinging object have maximum kinetic energy?

Back

A swinging object has maximum kinetic energy at the lowest point of its swing.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is directly proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

What is the significance of friction in energy conversion?

Back

Friction converts kinetic energy into thermal energy, often resulting in heat.
