Kinetic and Potential Energy

Front

What is kinetic energy?

Back

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

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly associated with gravitational and elastic potential energy.

How does height affect gravitational potential energy?

Back

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

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 happens to potential energy when an object is lifted?

Back

When an object is lifted, its potential energy increases due to the increase in height.

Where is potential energy greatest in a pendulum?

Back

Potential energy is greatest at the highest points of the pendulum's swing (positions 1 and 5 in a typical diagram).

What is the relationship between kinetic energy and speed?

Back

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

What is the least kinetic energy point in a pendulum's swing?

Back

The least kinetic energy occurs at the highest points of the swing, where the speed is momentarily zero.

How does compressing a spring affect its energy?

Back

Compressing a spring increases its elastic potential energy, as energy is stored in the spring.

Front

What happens to elastic potential energy when a spring is stretched?

Back

When a spring is stretched, its elastic potential energy increases, similar to when it is compressed.
