Force, Power, and Work

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is the unit of work?

Back

The unit of work is the Joule (J).

Front

What is the relationship between force, work, and distance?

Back

Work is the product of the force applied to an object and the distance the object moves in the direction of the force.

Front

What is power in physics?

Back

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

Front

What is the unit of power?

Back

The unit of power is the Watt (W).

Front

How is force calculated?

Back

Force is calculated using Newton's second law: Force = Mass x Acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the formula to calculate the force needed to lift an object?

Back

Force = Mass x Acceleration due to gravity (approximately 9.81 m/s²).

Front

If a person lifts a 60 kg object, what is the force exerted?

Back

Force = 60 kg x 9.81 m/s² = 588.6 N.

Front

What is the formula for calculating work done?

Back

Work = Force x Distance.
