What is an example of velocity and acceleration

Velocity is the speed an object takes to go from point a to point b.
Acceleration is a change in speed, wether a negative acceleration (slowing down) or positive (going faster)
The formula for velocity is: v=d/t
V is velocity, d is distance and t is time
you will get meters per segonds (m/s) which is a velocity.
The formula for acceleration is
a= vf-vi/t
a is acceleration, vf is final velocity, vi is initial velocity / (the slash) is a divider and t is time.
In the case of acceleration:
You will get t in s^2 (segonds square) or m/s^2 that's when you know there was an acceleration!

The first bit all depends on you frame of reference. You could say that a satellite (like the Earth) is traveling around the central point at a constant speed, yet constantly accelerating toward it. You can't say that for velocity, though, as it also specifies direction. (Unless you want to get tricky and start talking about curved space.) Someone before mentioned an object in free fall, but I disagree with that. It's still experiencing a force from gravity, but that force is being opposed so there is no resultant force, and thus, no acceleration. I think it's not possible to accelerate while maintaining a constant velocity. Part 3: simple. If something is accelerating in the opposite direction to the way it's traveling, it will come to a stop, the start moving in the other direction. Like, as mentioned above, a ball thrown up in the air.

Velocity is defined as a change in position over a certain period of time. If you are driving 50 mph then your velocity is 50 miles (a change in position) over hours (which is change in time). Also velocity isn't always just your speed, since velocity also indicates the direction in which the speed is occurring, so if you change your direction and not speed ( like going around a curve at a constant 50 mph) your speed may stay the same but you would have a change in velocity.
Acceleration is a measure of the change in velocity over a change in time. For instance if you jump out of a plane you will accelerate towards the ground at 32 ft/s^2. So every second that passes you will increase your VELOCITY by 32 ft/s. So while acceleration might remain constant you will experience a change in velocity until something stops that acceleration....like the ground.

When you go for a ride in the car, at first it is not moving therefor has no velocity. When someone steps on the gas the car accelerates up to the speed limit, say 45mph. The driver backs off the gas pedal just enough to keep the vehicle velocity at 45mph. If you come to a red lite then the driver must hit the brakes and de-accelerate back down to zero velocity. In this example the velocity is miles per hour, the acceleration is miles per hour per second.

velocity is a vector quantity which includes a direction and a magnitude(speed) and an acceleration is when u have a change in the one of the two (direction or magnitude).

Velocity and acceleration are vectors meaing they have direction. Speed is scalar.
