Chapter 14/15 Work, Power, and Energy

Two factors that determine work are

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

work is a measurement of how much force is applied over a certain

• distance
• velocity
• shape
• size

units of force are

• netwons
• grams
• joules
• meters

units for work are

• netwons
• joules
• meters
• seconds

if you push a cart with a force of 60 N for 2 m... how much work have you done

• 120 J
• 30 J
• 120 N 
• 30 N

work transfers

• sweat
• energy
• velocity
• effort
