Energy & Work Quiz

What is work in Physics?

• The distance an object is moved

• The force applied to an object

• The speed of an object

• The transfer of energy by a force acting on an object as it is displaced

What unit is mass measured in?

• Joules

• Newtons

• Meters

• Kilograms

Which of the situations require work to be done?

• None of the above

• Oleg lifts a 30 N box, 2 m from the ground

• 250 N Billy waits for the green man at the traffic lights

• Freya dances on the spot

In the Work Done formula

W (J) = F (N) x s (m)

What does the W mean?

• Work Done measured in Joules

• Force measured in Newtons

• Distance moved measured in meters

• None of the above

In the Work Done formula

W (J) = F (N) x s (m)

What does the s mean?

• Work Done measured in Joules

• Force measured in Newtons

• Distance moved measured in meters

• None of the above

In the Work Done formula

W (J) = F (N) x s (m)

What does the F mean?

• Work Done measured in Joules

• Force measured in Newtons

• Distance moved measured in meters

• None of the above

What is the equation for work done?

• W = F x s

• W = F - s

• W = F + s

• W = F / s

What is the relationship between work done, force applied and distance moved?

• Work done = force applied + distance moved

• Work done = force applied / distance moved

• Work done = force applied x distance moved

• Work done = force applied - distance moved

What is the weight of the chair if Kiran uses 2500J of energy by moving it 0.56m?

You will need to rearrange W = F x s

You are calculating the F (weight = force due to gravity)

• 5.6 N

• 7.8 N

• 2.5 N

• 4.464 N (4.5 kN)
