1.5 Newton`s Law of Motion
... Newton’s second law ( law of dynamics ) The rate of change of momentum of a particle is directly proportional to the resultant force acting on it. i.e. F ∝ d(mv)/dt or F = k d(mv)/dt If the mass is constant, F = kmd(v)/dt = k ma i.e. The acceleration of an object is directly proportional to the unba ...

What is a Force?
... An object will remain at rest unless acted upon by an “unbalanced” force. An object in motion will continue with constant speed and direction, unless acted on by an unbalanced force. This law shows how force, mass and acceleration are related as shown in the equation below: Force = mass x accelerati ...
