A vehicle’s velocity increases by 5 m/s every second. What does it mean?
Acceleration can be defined as the rate of change of velocity of an object with respect to time and in this case, the vehicle is also accelerating with a unform change in velocity.

An object starts from rest. It means that _____.
Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
