Total questions: 20
Worksheet time: 10mins
Abigail is pushing a box with a certain force over a distance. What is the formula she should use to calculate the work done?
work = force ÷ distance
work = force × distance
work = force + distance
work = force - distance
Aria, Evelyn, and Liam are studying physics. They are trying to calculate the work done when a force is applied to move an object. What is the SI unit they should use for their calculation?
joule
ampere
newton
watt
Evelyn is helping Grace move a heavy box. If Evelyn applies a force of 10 N to the box and it moves a distance of 5 meters in the direction of the force, what is the work done by Evelyn?
50 Joules
25 Joules
2 Joules
100 Joules
Michael is doing his physics homework and comes across a question about power. He knows that power is the rate at which work is done or energy is transferred. Which of the following formulas should he use to calculate power?
P = F/d
P = mgh
P = V/I
P = W/t
Scarlett, Evelyn, and Aria are participating in a science quiz. They are asked to identify the SI unit of power used to measure the energy consumed by the light bulb in their science lab. What is the correct answer?
volt
ampere
watt
ohm
Elijah is operating a machine that does 1000 J of work in 10 seconds. Scarlett and Anika are curious to know, what is the power of the machine Elijah is operating?
10 J
1000 J/s
100 J/s
10 J/s
Nora is driving a car. If the car exerts a force of 5000 N and moves a distance of 20 meters while Maya and Luna are watching, what is the work done by Nora's car?
100,000 Nm
200,000 Nm
50,000 Nm
10,000 Nm
Anika, Elijah, and Sophia are conducting a physics experiment. If Elijah uses a machine that does 200 J of work in 5 seconds, what is the power of the machine?
10 Watts
100 Watts
50 Watts
40 Watts
Aria applied a force of 50 N to push a heavy box. However, Mason accidentally pulled the box 10 meters in the opposite direction. What is the work done by Aria?
50 Joules
0 Joules
-500 Joules
500 Joules
Avery is operating a machine that does 500 J of work in 5 seconds. What is the power of the machine Avery is operating?
100 J/s
50 J/s
10 J/s
500 J/s
James was helping Kai to move a 100 J box to his new house. If James managed to move the box in 2 seconds, what was his power?
50 Watts
20 Watts
100 Watts
200 Watts
Emma, Avery, and Oliver are playing with a toy car. They notice that the car moves when they push it. How is this observation related to energy and motion?
Energy, like the push they give to the car, is required to cause or change motion.
Energy has no relation to the car's motion.
Energy is a result of the car's motion.
The car's motion is the only source of energy.
Emma, Abigail, and Maya are discussing the concept of energy and work. Emma says that energy is required to do work, and work is a result of energy. Abigail says that energy and work are unrelated concepts. Maya says that energy is a byproduct of work, and Abigail thinks that work is a form of energy storage. Who is correct?
Energy and work are unrelated concepts.
Energy is required to do work, and work is a result of energy.
Energy is a byproduct of work.
Work is a form of energy storage.
Avery is pushing a heavy box across the room. How is the energy related to the work Avery is doing?
Energy is only related to Avery's motion, not the work he is doing.
Energy is transferred to the box when Avery does work on it.
Energy is not related to the work Avery is doing.
Energy is created when Avery does work on the box.
Does work get done when you push a wall and it doesn't move? Explain.
Yes
No
Sometimes
Only if the wall moves
Which of the following give an example in which energy produces a force that causes motion?
Henry and Elijah are helping Hannah move into her new house. Would they do more or less work by lifting a box onto the back of a moving truck versus using a ramp, and why?
less work
it depends on the person
the same amount of work
more work
Abigail, Nora, and Avery are discussing the concept of work and energy. Nora says that work is done when a force causes an object to move. Avery says that work is done when energy is transferred. Abigail says that work is done when an object is at rest. Who is correct?
Work is done when a force causes an object to move.
Work is done when energy is transferred.
Work is done when an object is at rest.
Both Nora and Avery are correct.
What is the energy difference between a 60-watt light bulb and a 100-watt light bulb?
Henry and Emma are helping Abigail to organize her closet. They are stacking shoe boxes. How can they increase their efficiency?
Spend more time stacking boxes.
Stack fewer boxes per minute.
Slowly stack the boxes on a lower shelf.
Stack the boxes more quickly.
