Student Exploration: Inclined Plane – Simple Machine
Prior Knowledge Questions
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? A tool like a
dolly, lift, lever, etc.
2. Why would this help? It would help take some of the force off of 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? 260N
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 slides down slower.
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 force required? 150N
Activity A: Get the Gizmo ready:
Redirection of force Turn Off the External force. Click Reset.
Set the Angle to 30° and the Weight to 300 N.
Question: How does an inclined plane redirect a force?
1. Observe: Select the FREE-BODY DIAGRAM tab. Make sure Magnitude is on. A
free-body diagram is a picture that uses vectors to show the different forces
acting on an object.
