Question

what is motion and difference between speed..?? ​

Answer 1

A body is said be in motion or moving when it's position changes continuously with respect to a stationary object taken as reference point..

speed

speed of a body is the distance travelled by it per unit...

Answer 2

Answer:

DIFFERENCE between motion and speed are:-

motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time, and speed. ... The average speed is the distance with respect to time (a scalar quantity) ratio. Speed is ignorant of direction.

Explanation:

1. What is motion ?

1. Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

2. What is speed ?

2. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

speed formula :- S=d/t

S= speed

D= distance travelled

T= time elapsed
