Work Power

What is the relationship between work and energy?

• Work is a form of energy that can be stored.

• Work is a transfer of energy; when work is done, energy is transferred to or from an object.

• Work and energy are completely unrelated concepts.

• Work is the amount of energy required to move an object.

What is the equation for calculating power?

• Power = Work + Time

• Power = Work - Time

• Power = Work / Time

• Power = Work * Time

How can you tell if a force has been applied to an object?

• The object changes color.

• The object moves.

• The object makes a sound.

• The object becomes heavier.

How does increasing the distance affect work done?

• Increasing the distance while applying the same force increases the amount of work done.

• Increasing the distance decreases the amount of work done.

• Increasing the distance has no effect on the amount of work done.

• Increasing the distance requires less force to do the same amount of work.

What happens to power if the time taken to do work is reduced?

• The power decreases.

• The power remains the same.

• The power increases.

• The power becomes zero.

When is work considered to be done?

• When an object moves.

• When energy is transferred without movement.

• When a force is applied but no movement occurs.

• When an object is at rest.

What does it mean if no work is done on an object?

• The object moves without any force applied.

• The object does not move, even if a force is applied.

• The object is at rest and cannot be moved.

• The object is in motion but no energy is transferred.

What is the difference between power and work?

• Work is the total energy transferred, while power is the rate at which work is done.

• Power is the total energy transferred, while work is the rate at which power is done.

• Work and power are the same concepts and can be used interchangeably.

• Power is the energy used in a system, while work is the energy lost in a system.

What is kinetic energy?

• Kinetic energy is the energy an object has due to its motion.

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy an object has due to its position.

• Kinetic energy is the energy released during a chemical reaction.

What is the SI unit of power?

• Joule (J)

• Watt (W)

• Newton (N)

• Volt (V)
