For velocity to be truly uniform, the object must be moving in a straight line. If that is the case then the acceleration is Zero.
Acceleration is any change in velocity.
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
When an object is not accelerating at all. It has constant velocity.
Yes!!!
freefall
the rate at which velocity changes velocity=speed in a given direction
freefall
Yes, but only for an instant.
I assume you mean "non-uniform". "Uniform" simply means that the velocity (in this case) doesn't change.
velocity= distance/time=d/t accelaration= dv/dt
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
There are many formulas for acceleration, but the most basic one is: acceleration = change in velocity / time taken for velocity change
