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 of an object is doubled the acceleration will also be doubled. 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, we can determine the Acceleration is 0 because the speed and direction of the vehicle are not changing. The forces will cancel each other out. 3.
What are some error sources in the Second Law experiment? 1.
Weight of the string. 2.
The scale could be unprecise, or the stopwatch isn’t accurate

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. The equation above is used to calculate and find the acceleration by rearranging the equation so that we can solve for the a (acceleration)
