PS.6 States and Forms of Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is gravitational potential energy?

Back

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

Front

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 factors affect kinetic energy?

Back

Kinetic energy is affected by mass and velocity. The formula is KE = 1/2 mv².

Front

At which points does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at its highest points, which are positions A and D.

Front

At which point does a pendulum have maximum kinetic energy?

Back

A pendulum has maximum kinetic energy at its lowest point, which is position E.

Front

How does mass affect potential energy?

Back

The greater the mass of an object, the greater its potential energy when elevated to a height.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; doubling the speed quadruples the kinetic energy.

Front

What type of energy does a stretched rubber band demonstrate?

Back

A stretched rubber band demonstrates elastic potential energy.
