Ramp Inquiry Activity

Notes from Presentation 

How Do Ramps Help You Raise Objects? Inquiry Activity
Procedure
1. Make a stack of five books.
2. Make a ramp by leaning a short board against the top of the book stack. Place a sixth book against the bottom edge of the board to keep the ramp from moving.
3. Measure the height of the ramp.
4. Use a spring scale to pull an object up the ramp at a constant speed. Record the force indicated on the spring scale.
5. Repeat Steps 2-4 changing different variables.

Everyone will use a half sheet of paper to answer the following questions. This is your exit slip for today.
Think About It
1. Which situation required a greater force to pull the object?
2. How do you think the force needed to pull the object would change if the cart accelerated up the length of the ramp?
3. Explain why a box that is too heavy to lift can often be pushed up a ramp.
