Answer to Question #128869 in Mechanics | Relativity for Ariyo Emmanuel

Question

Define the following terms: (i) Displacement (ii) Velocity (iii) Acceleration (iv) Distance (v) Speed.

Answer 1

Displacement is the change in position of an object. It is a vector quantity and has a direction and magnitude. 

Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction.

Acceleration is the rate of change of velocity per unit time

Distance is The length of the actual path between the initial and the final position of a moving object in the given time interval 

Speed is the change in distance per unit time
