(a) In this type the effect of the force is MUSCULAR as the biceps contract. Also it is elastic as the spring moves back and forth and returns to original position
(b)Muscular force again.. also, the force in the balls direction either cancels out or makes the ball move in another direction
(c) In this type the effect of force is complete muscular force as we use our energy to stop moving a car. This also is the application when equal amount of forces act on each other from either side
(d) In this type the effect is that a stationary object starts to move and object accelerates
