Lab 3: Forces

For lab 3 we experimented with forces and motion and how they could affect and change the acceleration and velocity of an object. The final result of this was an experiment that monitored the change in velocity as more weights were added to double the amount of force being used to pull the slide, as can be seen below. In order to create a controlled and uncontrolled system to compare the results to we used compressed air to create a friction-less environment and then used the rail base to compare how friction can change an objects velocity.

To support these findings we also experimented with changing and varying the amount of newtons to pull a car and see how its acceleration changed, seeing that the value increase with the amount of force applied.

 

These experiments tied into the very first experiment we did where we experimented with changing the location and amounts of force exerted on a bowling ball to see how we could influence it. constant force would create constant acceleration while when provided with a much more loose or reduced friction environment, or constantly maintained force to produce a constant velocity. The secondary experiments supported this with the first one providing an example of changing force and the second and example of constant force, supporting the statement that all motion is based on the force behind it.
