This law state that ” The rate of change of linear momentum of a body is directly proportional to the applied force and the change takes place in the direction of the applied force”. Let F be the external force applied on the body in the direction of motion of the body for time interval […]
Momentum of a body is the quantity of motion poses by the body. It is defined to be the product of its mass m and velocity v. It is denoted by p. Momentum, P = mv SI unit of momentum is kgm/s. In CGS system gcm/s. It’s dimensional formula is [MLT⁻¹]. Variation Of Momentum Case-I:
Newton’s Law Of Motion Sir Isaac Newton (1642-1727) made a systematic study of motion and extends the views of Galileo. He arrived three laws of motion which are called Newton’s Law of Motion. These laws are as follows. Newton’s First Law Of Motion This law state that every body continuous in its state of rest
Galileo first asserted that objects move with constant speed when no external forces act on them. He arrived at this revolutionary conclusion on the basis of following simple experiments. (a) Galileo’s Experiments With Single Inclined plane Galileo first studies the motion of objects on an inclined plane he observed that (I) When an object moves
Force may be defined as an external agency (a push or a pull) which changes or tends to change the state of rest or of uniform motion or the direction of motion of a body. The dimensions of force is [MLT⁻²] and SI unit is Newton (N). A force applied on an object can produce
