Jan is moving to a new apartment. She needs to load her sofa and other large furniture into a moving van. The rear of the moving van is 1.5 meters high. 1. What could Jan use to make loading furniture on the van easier? She could use tools like a lever, pully, etc. 2. Why would this help? It would reduce the amount of force that is put onto Jan Gizmo Warm-up A simple machine can be used to make tasks like lifting heavy weights easier. One example of a simple machine is a ramp, or inclined plane. You can use the Inclined Plane – Simple Machine Gizmo to see how inclined planes can help to lift objects. On the CONTROLS pane, make sure the Angle is 30°, the Coeff. of friction is 0.00, and the Weight is 300 N. 1. The brick has a weight of 300 newtons (N). How much force would it take to lift the brick straight up? >300 N 2. Set the External force to On. A car appears, ready to push on the brick. Set the Applied force to 100 N and click Play ( ). What happens? It takes longer for the brick to slide down, but they both slide down the plane 3. Click Reset ( ). Using the Gizmo, find the smallest force that is required to push the block up the 30° ramp. What is the smallest [Show More]
