• 45,620 J
• 90,480 J
• 62,329 J

If 150 Joules of work is needed to move a box 10 meters, what force was used? 

• 1500 N
• 15 N
• 1.5 N
• 150 N

If 68 Joules were necessary to move a 4 Newton crate, how far was the crate moved?

A student needs 10 Newtons of force to lift a box to the top of a 2 meter shelf. How much work do they do?

• 12 J

• 8 J

• 20 J

• 5 J

A worker climbs a ladder and does 8 J of work on a 2 N object. What is the distance they lift the object?

• 18 m

• 4 m

• 10 m

• 6 m

Two factors that determine work are

• size of the force, and distance
• size of the force, and type of force
• mass, and distance

 Work done = Force x _________

• a. distance
• b. acceleration
• c. velocity
• d. speed

A force exerted over a distance to move an object is ______________________.

• power
• work
• momentum
• Watt
