1. A car is pushed 30m with a force of 400N. How much work is done?

2. How much gravitational potential energy is gained by lifting a 300N suitcase a height of 1m?

3. A bowling ball has a mass of 4kg and is moving at 8m/s. How much kinetic energy does it have?

4. A trolley is pushed with a force of 6N over a distance of 5m. How much work is done?

5. If you weigh 40kg, your weight is roughly 400N. How much gravitational potential energy do you gain to move a vertical height of 2.5m?

6. Which has the most kinetic energy: a car of mass 500kg at 20m/s or a car of mass 1000kg at 10m/s?
