Work, Power, Energy Practice

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d)

Front

What is the unit of work?

Back

The unit of work is the Joule (J).

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred.

Front

What is the formula for calculating power?

Back

Power (P) = Work (W) / Time (t)

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, calculated as PE = mgh.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on mass (m), height (h), and the acceleration due to gravity (g).

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 the difference between renewable and non-renewable energy?

Back

Renewable energy can be replenished naturally (e.g., solar, wind), while non-renewable energy cannot (e.g., fossil fuels).
