Work and Power

What is the difference between work and power?

• Work is the total energy transferred, while power is the rate of that transfer.

• Work is the force applied over a distance, while power is the total energy used.

• Work is the energy consumed, while power is the energy produced.

• Work is the speed of energy transfer, while power is the total energy transferred.

What does it mean if power is measured in Watts?

• It indicates the rate at which work is done.

• It measures the amount of energy stored.

• It represents the speed of an object.

• It quantifies the force applied to an object.

What is the unit of measurement for Power?

• Joules

• Watts

• Volts

• Amperes

What is the relationship between work and energy?

• Work is the transfer of energy.

• Work is the same as energy.

• Work is the opposite of energy.

• Work is a type of energy.
