Aperson is walking in a straight line for 10 s. the person has an initial position that is negative with respect to a chosen origin, and their velocity is also negative during the entire 10 s. at the end of 10 s, is the person closer to or further from the origin than they were originally? explain.

the answer is kevlar

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.
