Measure force on an Inclined Plane Worksheet

NAME___________________________

QUESTION:

HOW DOES THE ANGLE OF AN INCLINED PLANE AFFECT THE FORCE NEEDED TO MOVE AN OBJECT?

MATERIALS:

spring scale, wooden board, wood block, books to stack, worksheet, and pencil.

PROCEDURE:

  1. Make an inclined plane by laying the wooden board so the top part rests on the stack of books, and the other end lays on the ground. You have made an inclined plane.
  2. Use the spring scale to drag the wood block up the board until the top of the wood block reaches the edge of the stack of books.
  3. Students will record the force needed to drag the wood block up the inclined planes at different angles.

     NUMBER OF BOOKS        FORCE NEEDED TO PULL THE BLOCK UP THE
                                       INCLINED PLANE
    
          2 Books            _______________________grams(g)
    
          4 Books            _______________________grams(g)
    
          6 Books            _______________________grams(g)
    
          8 Books            _______________________grams(g)
  4. Use the spring scale to pull the spring scale up to the top level of the 8 stacked books-without using the board as the inclined plane. How many grams of force did it take to lift the block without using the inclined plane? __________________grams(g)
