Points to Remember

* Distance - The path taken by an object toreach one place from the other is called distance.

* Displacement – The straight line pathbetween two points is called displacement * Velocity is the rate of change indisplacement. SI unit of velocity is meter /second (m/s).

* Acceleration istherateofchangeinvelocity. SI unit of acceleration is m/s²

* Centre of gravity : The centre of gravity of an object is the point through which the entire weight of the object appears to act.

* Generally the centre of gravity of the geometrical shaped object lie on the geometric centre of the object.

* Stability is a measure of the body’s ability to maintain its original position.

* The three types of stability are : 1. Stable equilibrium 2. Unstable equilibrium 3. Neutral equilibrium.
