Newton's Third Law of Motion and Force of Gravitation - Is Newton's third law of motion applicable to gravitational force? Yes it is. Let us now see how Newton's third law of motion is applicable to the gravitational force existing between..

Let us now see how Newton's third law of motion is applicable to the gravitational force existing between the various objects in the universe. According to Newton's third law of motion to every action, there is an equal and opposite reaction. That is, if a body A exert..

Force is the external agent that changes the state of rest or uniform motion of a body along a straight lin..

Introduction - We have learnt about the motion of objects based on the definition of displacement, velocity and acceleratio..

W = FS cos q If the displacement S is in the direction of the force F, q = 0, cos q =1 Then, W = FS x 1 W = FS If q = 90 o , cos 90 o = 0 Therefore, W = FS x 0 = 0 i.e, no work is done by the force on the body. If a stone tied at the end of a string is whirled around i..

Question 1 - Question: Define force. Answer: Force is an external agent or influence, which changes or tends to change the state of rest or state of uniform motion of a body in a straight lin..
