Work, Energy, Power

Front

What is the formula for calculating work?

Back

Work = Force x Distance (W = F x d)

Front

What is the SI unit of work?

Back

Joule (J)

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, such as height above the ground.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred, calculated as Power = Work / Time.

Front

What is the SI unit of power?

Back

Watt (W)

Front

How does gravitational potential energy change with height?

Back

Gravitational potential energy increases as the height of an object above the ground increases.

Front

What is the formula for gravitational potential energy?

Back

Potential Energy (PE) = mass (m) x gravity (g) x height (h) or PE = mgh.

Front

What happens to kinetic energy at the highest point of a pendulum swing?

Back

At the highest point, kinetic energy is at its minimum (zero) and potential energy is at its maximum.
