The diagram shows the forces on an object. which best explains the movement? the force of friction is preventing the motion of the object. the push force is greater than the frictional force. the force of friction is slowing down the object’s movement. the push force is equal to the force of friction.

a.) travels faster in solids because the particles are closer together.

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.
