Presentation of Data:
Research Question 1:
Vx= 1.18x + 0
Slope: the cart accelerates by 1.18 m/s^2 for each Newton of net force Y-Intercept: 0 net force means 0 acceleration SIgn: positive, more net force means more acceleration Research Question 2:
Vx= inverse function
Slope: the cart accelerates by certain speed for every increase in mass Y-Intercept: none. the cart will always have a mass and acceleration |
Conclusion/Evaluation:
Research Question 1: The purpose of this lab was to explore the relationship between net force and acceleration of an object. In this experiment, the total mass of the system (cart and hanger combined) remained unchanged throughout. The experiment was performed by altering the distribution of weight between the cart and the hanger to see how the change in net force (the weight on the hanger) effected the speed of the cart. We determined that our hypothesis was correct in that as the net force increased, the acceleration increased. In other words, as we added more mass to the hanger from the cart, the speed of the cart increased.
Research Question 2: The purpose of this lab was to explore the relationship between mass and acceleration of an object. In this version of the experiment, the total mass of the cart was altered by adding weights during each trial while the mass of the hanger remained constant throughout. By altering only the weight of the cart, we were able to determine that our hypothesis was correct. As mass increased, the acceleration decreased. In other words, as we added more mass to the cart, the hanger got lighter and was able to pull on the cart less.
Both: Overall, these two experiments had the purpose of determining the equation for net force. We learned that net force equals mass times acceleration.
