Two factors that determine work are

• amount of the force, and effort used
• amount of the force, and type of force
• mass, and distance
• amount of force and distance moved

You apply a force of 18 N to a dresser and move it 3.0 m. How much work did you do on the dresser?

• 6.0 J
• 54 J
• 27 J

The unit or label for work is

• netwons
• joules
• meters
• seconds

if you push a cart with a force of 60 N resulting in 120 J of work.. how far did you move the cart? 

• 7200 m
• 0 m
• 2 N 
• 2 m

 Work done = Force x blank?

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

units of force are

• netwons
• grams
• joules
• meters
