Now, in the Tracker tool, add kinetic energy, KE, and potential energy, PE, to your table. (Click on Table, then check KE and PE in the Table Columns dialog.) Also, adapt the two graphs to show kinetic energy and potential energy vs. time. (Click on the
vertical axis labels; from the pop-up menu, select KE or PE.)
Step forward through the video a frame at a time, tracking the process in the table and on the two graphs. Based on your
observations, what can you say about your predictions in Part A and Part B concerning the potential and kinetic energy?

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
