What is kinetic energy?

Back

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

Front

How do you calculate kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction.

Front

What is the relationship between speed and kinetic energy?

Back

Speed has a significant effect on kinetic energy; as speed increases, kinetic energy increases exponentially since it is proportional to the square of the speed.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What factors affect potential energy?

Back

Potential energy is affected by the mass of the object, the height above the ground, and the acceleration due to gravity.
