5. Which does not describe a force pair? а SC.6.P.13.3 A When you push on a bike's brakes, the friction between the tires and the road increases. B a a When a diver jumps off a diving board, the board pushes the diver up. © When an ice skater pushes off a wall, the wall pushes the skater away from the wall. D When a boy pulls a toy wagon, the wagon pulls back on the boy.

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.
