In many situation the shape and size of an object are not relevant. The properties of such an object can be lumped in a point particle. Even objects that are clearly extended such as stars and planets are often well approximated by point masses. In the case of subatomic particles, such as electrons, we are physically unable to determine …
WebThe word displacement implies that an object has moved, or has been displaced. Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation: \text {Displacement}=\Delta x=x_f-x_0 Displacement = Δx = xf − x0. x_f xf refers to the value of the final position.

Webmass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force.
