• • Bell ringer (written): How much work do you do if you push a car 50 meters using 200 Newtons of force? How much work would you do if someone applied the brakes to that same car, so you were unable to move the car.

  • Notes - work

    • Work is done (in physics) when a force is applied to an object and that object moves in the direction of the force.

    • Work is measured in Joules (J)

    • Work = force x distance (Work in Joules, force in Newtons, and distance in meters)

  • Calculating work activity
