Name: Period: Unit 8:2 1. Energy A. The units for work and energy. 2. Joules B. Stored or gained work. Is energy increased or decreased? An object speeds up. An object is lowered back to the ground. C. Energy changing from one form to 3. Work another. D. Energy transferred by forces. Product of force and distance. 4. Power Friction slows down an object. An object sits motionless on a table. 5. Energy Transfer E. How fast work is done, An object is lifted up from the ground. Potential Energy (E,), Kinetic (E,) Energy, or Work (W) Figure out the Energy Transfers. Thermal; Nuclear; Radiant: Mechanical; Chemical: Electrical An object is pushed for 3 m. An object is going 6 m/s. Eating food allows you to move. Slowing down an object. An object on top of a 3 meter table. A gas stove boiling water. Friction stopping an object from moving. What kind of energy is lost from A to D? Which forces are doing work on the object? What kind of energy is lost from D to G? Which forces are not doing work on the object? F1 4 kg A person holds onto a 25 N object for 2 minutes 3 m above the To help a bicyclist get to the top of a hill, they speed up. Using ground. How much work is done on the object? energy, explain why this helps. A 30 N force pushes a 20 kg box 5 m across the floor. How much work is done on the box? If the bicyclist starts at rest, how do they get up the hill? What did the above work become? 3 m 6 kg A 25 N force pushes a box up a ramp to the back of a truck. If the force does 200 J of work, how long is the ramp? What kind of energy will it have at the top? Calculate it. Where does the work go? Where does this energy come from? V = 20 m/s 10 m/s 0:05.0 0:00.0 Motor A does 240 J of work in 24 seconds. Calculate power. F = 40 N י 5m 10m 15m 20m 25m Motor B does 240 J of work in 8 seconds. Calculate power. Calculate the work done on the car. Which motor did more work? Calculate the power of the force. Which motor was more powerful? True or false: “A more powerful motor does more work"? What did the work become? cstephenmurray.com Legal copying of this worksheet requires written permission. Copyright © 2007, C. Stephen Murray
