Answer: v=u + at
v (Velocity) = u (Starting velocity) + a (acceleration) x t (time)
So, starting from stationary (u=0), the velocity is simply a x t
e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph.
Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.

What is the acceleration in science if you know average speed and time?
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
Example of derived quantity?
velocity work force acceleration
What is the formula for velocity if you don't know the distance?
You need to know the change in distance between two points in time, not the distances [from a fixed point] themselves. If you know the initial velocity (u) and acceleration (a), then you can work out the velocity (v) after t units of time as v = u + at
How velocity of an object can affect the work done by the object when moving up and inclined?
work = force * distance and force = mass * acceleration and acceleration = change in velosity/change in time so work = mass * acceleration * distance , as a result work = mass * change in velosity/change in time * distance, hence the velocity of the object affected by : 1.mass of the object. 2. gravitational acceleration which reduces the speed of the object when go up and increases the speed of the object when it come down.. 3. look at the rules etc........thx..............with best regards
How can you find velocity from only force and mass?
You would need to use the equation f=ma In this equation, f means force, m means mass, and a means acceleration. So dividing the force by the mass will give you a figure for acceleration. If you know how long the object has been accelerating for, or how far, and what the initial velocity was (or whether it started off still) then you can work out the velocity from this acceleration.
