for the first few seconds the object is in rest because the position curve is parallel to x-axis. then it moves forward with a constant velocity because it's slope is constant for some time. then again position curve is parallel to x-axis so it again in rest. after that, it moves in opposite direction with constant velocity. constant velocity is due to the slope is constant and the opposite direction is due to the negative slope.

1. To confirm the linear relationship between acceleration and force, established by Newton's Second law, a student collected data. Using the collected data he made a plot of system's acceleration vs applied force. The mass of the moving system remained constant during the experiment. This graph will be used for the following questions: 1; 2; 3; 4. Determine the experimental mass of the system using the information provided in the graph: acceleration vs applied force. Submit answer in kilograms. Use...

Observe the graphs of the motion. Consider only the portion of the graph from just after the cart was released to just before it was stopped. Find the position on each graph where the cart turned around and started back down. What is the value of the velocity at that point? What is the value of the acceleration at that point? Is there any significant difference between this acceleration graph and the acceleration graphs from steps 15 and 18? Why...

If you were to plot the coulomb’s law formula on a graph , where the slope is equal to kq1q2. Y axis is F and x-axis is 1/r. The equation for the graph is a linear equation where m=slope and b=intercept. What is the meaning/value of this intercept. Example Graph : F vs 1/r y= mx + b y=(k*2.6x10^-9)x + 2.3x10^-6 Where m=kq1q2 , what would b represent ?
