Work Calculations

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

How do we calculate work?

• W = F * d
• w = f * D
• W = F * D
• w = f * d

• 85,200 J
• 45,620 J
• 90,480 J
• 62,329 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
