FC: Physics Lab Report | Kristen C. Nelson M. Victor A. March 16, 2012 10th

1: Introduction | In this project we will be using the Newton's second law of motion to determine the force in X and acceleration used to moved the carts that will be used. F=ma a= F/M

2: Objectives | Find the force in X and acceleration needed to pull the cart. Both alone and with kids inside.

3: Procedure | 1. Weigh both the cart and the kids to get their mass in Kilograms. 2. Using the heavy duty spring scale measure how much force is needed to move the cart alone and measure it's angle with a protractor. 3. One the first trial you'll only place kid1 (Valeria) into the cart. Measure the force and angle needed to move the cart and do so as well for all three trials used for her.

4: Procedure 2 | 4. In trial two only kid2 (Maria Fernanda) Will be used in this trial. Like the previous one, you will measure the force and angle used to pull her in the cart and repeat making 3 trials for her in total. | 5. In trial three, both kids will be placed into the cart. Like the previous two, you will measure the force and angle required to pull them both while they are inside the cart. Like the previous two, 3 trails will be required for this one as well.

5: 6. Once all this information has been collected, use it to find both the force in X and acceleration that was used to move the carts. For each of the trials. And the three trails in each of these.

6: Results

8: Conclusions

9: Even if the force applied is similar. The greater the angle in which it's applied the less force in X will be used.
