What happens to the dots when an objects stops for a period of time? Arrows just stop but dots keep going

Dots stack up for a give amount of time

Nothing the Motion Map just stops

Arrows change directions on a different line

v 154.9= 0.9 length length s little over 154.9cm

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.
