How much work is done if I use 5 Newtons of force to move an object 2 meters?
Formula: Work= force x distance
                  Joules= Newtons x meters

• 10 Joules
• 15 Joules
• 10 Newtons

How much work is done if I use 6 Newtons of force to move an object 3 meters?
Formula: Work= force x distance
                  Joules= Newtons x meters

• 15 Newtons
• 18 Joules
• 9 Joules
