    The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.

    On the circular turns the outer edge of the road is kept higher than the inner edge such roads are called banked roads. banking of roads helps the vehicles to cross the turn safely because by banking of roads the component Rcos thita of normal reaction R starts acting towards centre of circular track which provides the vehicle required centripetal force

    Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.Distance is the length covered .with respect to time.

    Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.Displacement can be zero.

    At a point Where the whole Mass of the body concentrated is known as centre of mass

    0Thank You

    Dipen Saka 8 years, 2 months ago

    In <a href="https://en.wikipedia.org/wiki/Physics" title="Physics">physics</a>, the center of mass of a distribution of <a href="https://en.wikipedia.org/wiki/Mass" title="Mass">mass</a> in space is the unique point where the <a href="https://en.wikipedia.org/wiki/Weight_function" title="Weight function">weighted</a> relative <a href="https://en.wikipedia.org/wiki/Position_(vector)" title="Position (vector)">position</a> of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. Calculations in <a href="https://en.wikipedia.org/wiki/Mechanics" title="Mechanics">mechanics</a> are often simplified when formulated with respect to the center of mass. It is a hypothetical point where entire mass of an object may be assumed to be concentrated to visualize its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion
