Work Work Work Work Work Work

True or false
You do work only when you exert a force on an object and move it

• true
• false

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

When you change the ? and the ? of an object you transfer energy to that object...

• position and speed
• size and shape
• speed and velocity
• distance and velocity

both work and energy are measured in 

• joules
• newtons
• meters
• seconds

energy in motion

• kinetic
• potential
