Does velocity equal acceleration x time?

Answer 1

Yes, sort of. At least, that's the units used. The actual definition of acceleration is:

a = dv/dt

In other words, the rate at which velocity changes. In the case of constant acceleration, that would be equal to a change in velocity, divided by the time interval during which this change takes place. In the case of non-constant acceleration, the acceleration, or rate of change of velocity, can of course change from one moment to another.

Answer 2

No, velocity is the rate of change of displacement, while acceleration is the rate of change of velocity. The equation that relates velocity, acceleration, and time is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.

Answer 3

Yes. (if the initial velocity is zero)

if not then velocity = initial velocity + acceleration x time

Answer 4

Yes.
