Jenny is doing her homework. When Jenny wrights the pencil exerts a force of 5N on the paper the area of the pencil in contact with the paper is 0.5mm squared calculate the pressure kg the pencil on the paper. Give the unit

momentum of soft ball three times less than baskey ball

answer; how far out of place which the object finished relative to the starting location;

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.
