Work and Power

Front

What is the definition of work in physics?

Back

Work is defined as the measure of energy transfer that occurs when an object is moved over a distance by an external force. It is calculated as the product of the force and the distance moved in the direction of the force.

Front

What is the formula for calculating work?

Back

The formula for work (W) is W = F × d, where F is the force applied and d is the distance moved in the direction of the force.

What is one joule equivalent to in terms of newtons and meters?

Back

One joule is equivalent to one newton exerted over a distance of one meter (1 J = 1 N × 1 m).

Front

What is the definition of power in physics?

Back

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

Front

What is the formula for calculating power?

Back

The formula for power (P) is P = W / t, where W is the work done and t is the time taken.

Front

What is one watt equivalent to in terms of joules and seconds?

Back

One watt is equivalent to one joule per second (1 W = 1 J/s).

Front

How do you calculate the power required to do a certain amount of work in a given time?

Back

To calculate power, use the formula P = W / t, where W is the work done and t is the time taken.

Front

What is the relationship between work and energy?

Back

Work is a means of transferring energy from one system to another. When work is done on an object, energy is transferred to that object.

Front

What is force in the context of work and power?

Back

Force is a push or pull acting upon an object, measured in newtons (N), that can cause the object to accelerate or change its motion.

Front

What is the unit of work?

Back

The unit of work is the joule (J).
