Work, Power, Energy

Front

What is work in physics?

Back

Work is done when a net force causes an object to move in the direction of the force.

Front

What is the formula for calculating work?

Back

Work = Force × Distance × cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the unit of work?

Back

The unit of work is the Joule (J), which is equivalent to one Newton meter (N·m).

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 = Work / Time.

Front

What is the unit of power?

Back

The unit of power is the Watt (W), where 1 Watt = 1 Joule/second.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

How does kinetic energy change with velocity?

Back

If the velocity of an object is doubled, its kinetic energy increases by a factor of four.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.
