Energy and Work

Front

What is the equation for calculating work done by a force?

Back

W = F × d, where W is work, F is force, and d is distance.

Front

What type of energy does a baseball held by a pitcher have?

Back

Potential Energy.

Front

What happens during energy transformations?

Back

Energy changes from one form to another.

Front

What two factors does kinetic energy depend on?

Back

Speed and mass.

Front

What is stored energy waiting to be used called?

Back

Potential Energy.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 m v², where KE is kinetic energy, m is mass, and v is speed.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy.

Front

What is work done when a force is applied but there is no movement?

Back

Work done is zero because W = F × d and d = 0.

Front

What is the unit of work in the International System of Units (SI)?

Back

The unit of work is the Joule (J).

Front

What is an example of energy transformation?

Back

A battery converting chemical energy into electrical energy.
