give reason froce can stop a moving object
Answers
Definition of the Force ⇒ Force is a Push or Pull which can produce motion in a body or either stop a body.
From its Definition, It can be Made Clear, that when force acts on a body it displaces the body or either it stops.
But, One point should be noted that Force can only Displaces a Body or stops when the magnitude of the Force applied will be Greater than the Magnitude of the Limiting Friction or the magnitude of the kinetic friction respectively.
If the Force acting on the body is less than the limiting friction then there will be no displacement. For example, if we push the Wall, it will not move but the Force is acting on it. The Reason is that, Norma Reaction of the wall is greater since its mass is more as a result friction becomes larger.
But in case of the small object, mass is less, therefore, Normal reaction is less, Hence, Friction is also less. Thus, Body can be easily moved or stopped by applying a Force greater than its limiting friction. or Kinetic Friction respectively.
Formula to Calculate Limiting friction is,
F lim. = μN
where, F is the limiting friction and μ is the coefficient of the Static Friction and N is the Normal Reaction.
Hope it helps.
