Kinetic and Potential Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

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 is the relationship between kinetic energy and speed?

Back

Kinetic energy is proportional to the square of the speed; as speed increases, kinetic energy increases exponentially.

What type of energy is associated with a stretched spring?

Back

The energy associated with a stretched spring is called elastic potential energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; if the mass of an object doubles, its kinetic energy also doubles, assuming constant speed.

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh.

What is the principle of conservation of energy?

Back

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