1. Work
Work is an amount of force applied to an object making it move a certain distance
*If an object doesn’t move, no work is done

2. Work As such… W = F × d (Work = Force × distance)
Units of work are joules where 1 joule = 1 kg·m2/s2 = 1 N·m (Newton-meter)

3. Work Practice Problems
1. While out with friends, someone’s car runs out of gas. They apply a cumulative force of 1080 N to push the car 210 m to the nearest gas station. Determine the work done on the car.
2. Someone is using rope to horizontally pull an object across an icy pond. They pull the object 5 meters using 10 J. How much force was applied to the object?
3. A powerlifter applies 3000 N of force to do 2600 J of work lifting a barbell off the floor. How high did they lift the barbell?
