Year 10 Pathway C Mr. D. Patterson 1

Define work as the product of pushing an object (F) over a distance (s) Solve problems using W = Fs = mas 2

Lifting a pen off the floor or lifting a brick off the floor? Pushing a wheelbarrow across a driveway or pushing the same wheelbarrow up the street? What makes each one require more work?

Work is the product of the displacement an object moves and the net force applied to the object in that same direction. W = work (J) F = force (N) s = displacement (m) m= mass (kg) a = acceleration (ms -2 )

How much work is done dragging a body for the mafia with a force of 30 N for 200 m? 5

How much work is done pushing a macbook air up Mt Everest? hint: Mt Everest is 9 km high and a macbook air has a mass of 1 kg 6
