Work Done and Power _ GCSE Physics

What is required to calculate the amount of work done?

• Force and time

• Distance and time

• Time and speed

• Force and distance

In the example, how much work is done when a box is pushed with a force of 300 Newtons over 2 meters?

• 1200 joules

• 600 joules

• 300 joules

• 900 joules

Why is it incorrect to say the second person did more work because they took less time?

• Because they used more energy

• Because work is not dependent on time

• Because the force was different

• Because the distance was different

How is power calculated in this context?

• By subtracting distance from force

• By multiplying work done by time

• By adding force and distance

• By dividing work done by time

If one person exerts 30 watts and another 60 watts, what does this indicate?

• The first person did more work

• The second person did more work

• Both exerted the same power

• The second person exerted more power
