Notes

**Newton's Second Law Of Motion Lab Report**

Materials

Recycled Car

Ramp

4 Text Books

Meter Stick

Stop-watch

Calculator

Journal (or somewhere to record data)

Weights (100g., 200., and 300g.)

1. Set up ramp by putting the 4 text books on the floor and placing the ramp on top of them. Place the meter stick of the end of the ramp.

2. Place your first weights (100g.) on your car.

3.Placeyour car on top of the ramp where the start line is.

4.Have someone start the stopwatch, while you let go of the car.

5.Stop the stopwatch once the car has reach the 2 meters.

6. Record time one the your data table.

7. Repeat steps 1-6 3 times with the same weight. Then repeat steps 1-6 with the 2 weights (200g. and 300g.) 3 times each.

Conclusion

This lab investigated if Newton's Second Law of Motion was accurate when tested. In order to study the problem we used recycled cars and tested three different weights to see which needed more force. The results showed that the more mass an object has the more force it will need, which proved my hypothesis. I believe my results are accurate because my data table and graph show that if you have 100g. you will need less force to move the object than if the object's mass was 300g. .

Introduction: (Research)

Newton's Second Law of Motion states that the greater mass an object has, the more force is required to move it. This is the only law that has a mathematical equation (F=ma).

Purpose/Problem

The purpose of this lab was to learn and demonstrate how Newton's Second Law of Motion works.

If the car has more mass then it will need more force to move.

Question

Which mass will need the more force to move?

Variables:

Independent Variable:

Distance (2m.)

Dependent Variable:

Mass (100g.,200g.,300g.,)

Hypothesis

Steps

Observations and Data

Make sure to get your hypothesis stamped by your teacher.

Demonstrating Steps

Make sure to know how to calculate speed (distance over time) and force (mass times acceleration)

Show your teacher the data table when completed to receive credit.
