Consider three properties of the net force on an object: a magnitude, direction, and angle with respect to the objects path. For the following situation select the choice that indicates wether these quantities are constant or changing during the course of the motion. 1. The magnitude and the angle of the net force with respect to path are constant, but the direction is changing

2. The direction and the angle of the net force with respect to path are constant, but the magnitude is changing.

3. The magnitude and direction of the net force are changing, but the angle of the net force with respect to path is constant.

4. The magnitude, direction, and angle with respect to path for the net force are constant.

5. The magnitude and direction of the net force are constant, but the angle of the net force with respect to path is changing.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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.
