Equation of Motion
There are three important equations which are used to solve the problems about the motion of bodies. These equations show the relation between initial velocity, final velocity, acceleration, distance and time. These are known as equations of motion. It is necessary to mention that in these equations
- Motion will always be taken along straight line.
- Acceleration will be uniform.
- Although velocity, acceleration etc. are vector quantities but in these equations their magnitude will only be considered.
- Initial velocity will be taken as positive. Other quantities which are in the direction of initial velocity will be taken as positive and in the opposite direction will be taken as negative
