Activity B (continued from previous page) 7. Predict: Work is done whenever a force causes an object to move, increasing the object's mechanical energy, which is the sum of its potential and kinetic energies. As you have earned, an inclined plane has a mechanical advantage because it makes it easier to lift an object, but do you think an inclined plane helps you to do less work? Explain your answer. 8. Calculate: If the distance moved is in the same direction as the force, the work done by a force equals force x distance. Work can be measured in newton-meters (N.m) or joules (J). Select the SIMULATION tab. Click Reset. Set the Angle to 37, Coeff. of friction () to 0.00, and the Weight to 450 N. Move the brick so that its Height is exactly 1.00 m. A. What force is needed to lift the brick vertically? B. The top of the ramp is 3.01 m above the ground. How far does the brick need to be lifted vertically to reach this height? C. How much work does a forklift do when lifting the 450-N brick from 1.00 m to 3.01 m if it uses the least force necessary for lifting? ent eviando be 9. Compare: Use the Gizmo to find the minimum force needed to lift the brick. Set the Applied force to this value and click Play. A. What force is needed to push the brick up the ramp? B. Select the WORK tab. What is the total distance the brick was pushed to reach the top of the ramp? C. How much work was done on the brick by the car
