Una masa de 0.3 Kg está sobre una mesa horizontal cuyo coeficiente de rozamiento es 0.2. una cuerda que pasa por una polea une a esta masa con otra, de 0.2 Kg, que cuelga libre por fuera del borde de la mesa. Si la cuerda y la polea son ideales, calcular: a) La aceleración del sistema. b) La tensión de la cuerda. Nota :(MOVIMIENTO EN SENTIDO HORARIO)

d. 1,018 in.2

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.
