Movement of any object from one position to another with respect to an observer is known as Motion. Position – Motion of any object is defined by its position with respect to the observer. Position...
Suppose an object having mass m has an initial velocity u and after certain time t it attains a velocity v. Now momentum P1=mu and P2=mv So change in momentum =P2-P1=mv-mu =m(v-u) So the rate of change...
First law: In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force. Second law: In an inertial reference...
