Velocity is just a fancy word for the speed an object is move at any given time...and acceleration is the increased forward rate at which an object is speeding up.

velocity is a constant speed in a single direction where velocity = displacement / time
acceleration is a change in the velocity. This means it could be either slowing down or speeding up in EITHER direction.
Acceleration can be found using a multitude of formulas, but my personal choice would be taking the final velocity after a set time, subtracting the innitial velocity and then dividing all of that by the time it took to go that distance.

Velocity is similar to speed. It's the rate of displacement over time. Acceleration is how that rate changes. If you had a velocity of 50 m/s and were accelerating at a rate of 5.0 m/s^2, in one second you would be going 55m/s, in two 60 m/s, etc.

speed is the fee of exchange of displacement of any merchandise in a single specific course. yet , the acceleration is the fee of exchange of speed. the two speed and acceleration are vector parts. So the "exchange in speed' may be the exchange in the two displacement or course. Thast ability, whether there is not any exchange interior the fee of the speed, by way of fixing the course additionally there could be "acceleration". This what's unquestionably occurring interior the around action - The physique is shifting in uniform speed yet changing its course contiuously. subsequently it has have been given an acceleration. with regard to the "internet stress" . If the physique is shifting in uniform speed with none stress to triumph over(as whether this is shifting in area the place there is not any stress like: friction, air resistance, gravitational pull and so on,) there is not any internet stress. (undergo in recommendations Newton's first regulation). yet, if a automobile shifting in a undeniable street with uniform speed, it has to triumph over the frictional stress, air resistance, small climbs the place it has to triumph over the gravitational stress, actual a stress is to be utilized to triumph over those forces. For a freely falling physique, the acceleration is continuous throughout.whether this is on the tip of the 5th 2nd or 10th 2nd. For a physique thrown vertically upwards, The preliminary speed (u)= 30 m/s on the suitable of the trajectory, the speed(v) = 0 m/s Time taken (t)= 3 sec Acceleration (g) = - 10 m/s^2 Distance(top) travelled = H = ut + a million/2 gt^2 . . . . . . . . . . . . . . . . . . . . . . = 30 x 3 + a million/2 x(-10)x 3^2 . . . . . . . . . . . . . . . . . . . . . = ninety - (a hundred x 4.5) . . . . . . . . . . . . . . . . . . . . . .= ninety - 40 5 = 40 5 m . . . . . . . . . . . . . . . . . ======================

You could have gone to wikipedia and learned this, however I will help someone with homework just once.
Velocity is speed at a given time. Example the car was travelling at 100 mph. Acceleration is a function of a change in velocity over time as speed increases.
Try the library some time, or your textbook.

Velocity is like speed, but with direction. Acceleration is the rate at which the velocity is changing.

I can't give you an extremely technical answer, but according to what I remember from high school...
Acceleration is the rate of change of speed. Another way to say this is: Acceleration is the ratio between distance covered and time elapsed.
Velocity is acceleration with the added factor of direction. So, you cannot have simply a rate of speed or speed change, you need a direction or vector of direction to state velocity.
Hope that helps. :)

Velocity is a measurement of speed and direction in which something is traveling. ie, 10 m/s Due West.
Acceleration is the rate of increase or decrease of speed that occurs over a stated amount of time, ie 3m/s squared.

Velocity is a speed at a given time. You either use intial velocity (the velocity at one given moment) or the average velocity, which (you guessed it) is the average of the velocities you are using.
Acceleration is the RATE of which something is getting faster or slowing down.
The formula for instanteous velocity (one of them anyways) is v= (change in position)/ time
Acceleration= (change in velocity)/ time

Velocity is how fast ur going and acceleration is if u get any faster or slower
