Proving Newton’s Second Law

 

Question

What is the relationship between force, mass and acceleration?

 

Materials used

·         …

2 spring scales, table ramp, metal car, weights, books and a table                           

Hypothesis

I think that force and mass strongly affect acceleration. It affects the speed of the object.

 

Procedure

1.)    First gather materials

-2 spring scales

-table ramp

-metal car

-weights

-books

-table

 

2.)  Set up the table ramp. Put block of wood onto books. The amount of books underneath determines the angle. As shown in the diagram.

 

3.)    Now attach a spring scale to the metal car

 

4.)    Add weights into the car. You can choose

              the amount of weights you want.

 

5.)    Next, pull on hook on spring scale, which will pull the car up the ramp. (On the spring scale, there will be a number and whatever the line is on is what the force is)

 

6.)    After determining the force, repeat the same process with different weights in the car.

 

7.)    Once you’ve done enough procedures and have enough data, graph all of your data in a line graph- force and mass on one and angle and acceleration on another graph.

 

8.)    Make sure units are correct and your data is put together.

 

9.)    Once completing the lab, clean up all of the materials carefully.

Conclusion and Analysis

From doing this lab, I learned that force and mass basically controls and affects acceleration. This lab was interesting to ma and I learned a lot.
