Question

In the game of football sometimes we collide with a player of the opposite team. Both

feel hurt because each applies a force to the other. There is a pair of forces. The two

opposing forces are action and reaction forces. It is important to note that even

though the action reaction forces are always equal in magnitude these forces may

not produce accelerations of equal magnitudes.

a. Which law of motion explains about this action reaction pair?

b. What is the magnitude and direction of action – reaction force pair?

c. When a gun is fired, the acceleration of the gun is much less than the acceleration

of the bullet. Why?

d. While playing football, if you happen to collide with your friend, who has more weight

than you, who will get more hurt and why?​

Answer 1

Answer:

a) Newton's third law of motion

b) action reaction force pair are both equal and opposite but they always act on different bodies not on the same one

c) because of conservation of momentum

the body having smaller mass attains more velocity

d) obviously you

although the forces are equal and opposite

but it would have a greater effect on the body of smaller mass

which proves the line in your question that the work done or the acceleration produced by action reaction pairs might not be equal
