Question

what can you say about the speed of a moving object if no force is acting on to it

Answer 1

The speed, or actually the velocity, of a moving object, if no force is acting on it, will be in a straight line with a constant speed (no acceleration), as required by the First of Newton's laws.

Answer 2

Answer:

speed is constant and in same direction.

Explanation:

if no force is acting on it,

F net external=0

therefore

m*a=0

therfore

a=0

i.e. (v-u)/t=0

therfore v-u=0
