According to Newton's Second Law F = ma. If the force applied to an object is doubled, what happens to the acceleration? If the force applied to an object is doubled, then the acceleration also doubles. Question 2: You observe a vehicle traveling on a highway. The vehicle is maintaining a constant velocity. What can you determine about the forces on the vehicle? If a vehicle is maintaining a constant velocity, then there would be no net force being exerted on the moving vehicle. Question 3: What are some error sources in the Second Law experiment? Some of the error sources that could have been in this experiment is, not getting proper stopwatch time from moment let go from the .62 start line or at stop line since the cart moved very fast. Question 4: In the Second Law experiment, the acceleration is calculated by measuring the time for the cart to move from the start point to the end point and applying the kinematics equation: Explain how this equation is used to find the acceleration. To find the acceleration the equation must be changed to the following equation: a=2s/t. in this case, s is equal to our d value, since our table we doubled our distance and divided it by the average time squared, which the new equation above would do for us as well.
