Question

If the force is applied opposite to the motion, what will happen to the speed of the object ?

Answer 1

IF FORCE IS IN OPPOSITE DIRECTION OF MOTION THEN THEIR WILL BE TWO CASES-

FIRST CASE-

IF THE FORCE APPLIED IS GREATER THAN THE MOTION IN THAT PARTICULAR OBJECT, THEN THE MOTION WILL GET REVERSED.

SECOND CASE-

IF THE FORCE APPLIED IS LESSER THAN THE MOTION IN THAT PARTICULAR OBJECT, THEN THE MOTION WILL GET CONTINUE BUT ITS SPEED WILL BE REDUCED..

Answer 2

If the force is applied in the direction opposite to the direction of motion, it opposes the motion of the object and hence the speed of the object decreases
