what's the difference between uniform acceleration and uniform velocity?

Question

in detail please........

Answer 1

Well I was always a little baffled by the difference between acceleration and velocity; but this is how I keep it clear in my head.

Velocity is just a fancy way of saying speed EXCEPT that it also means that the speed measured is travelling in a particular direction.

IOW, Velocity= (change in distance)/ (change in time).

Acceleration on the other hand is the second derivative of velocity, which is ANOTHER fancy way of saying:

Acceleration= change*(change in distance)/ (change in time)

So back to your question... Suppose you're driving your car South down the interstate highway at a constant speed of 45 miles per hour. This would be considered your uniform velocity.

The further you get from the city the number of cars lighten up, it's a beautiful day, and you have the top down in your sports coupe. IOW you decide to hit the pedal and drive a little faster, say 65 mph. The change in speed from 45mph to 65 mph would be considered the uniform acceleration.

So there you go, examples and equations...

Phew, Hope I helped!!

Answer 2

Uniform Velocity And Uniform Acceleration

Answer 3

Uniform Acceleration- it when the velocity is changing constantly.. Say u are driving a car and every second your speed is increasing by 2m/s. Hence u are normally speeding up or down constantly.

Uniform Velocity- Its when the speed is the same (and direction). It means that when u are driving a car you are at 30miles/hour constantly. u dont increase the speed or reduce it. To complicate it a bit further, u have to be moving in the same direction. say you are moving in a circle with the same speed, then u dont have a uniform velocity as u are not moving in the same direction

Answer 4

acceleration is the difference of the veolocity for simplicity sake. So if acceleration is uniform, that is to say the increase in speed every second is the same throughout.

For uniform velocity, it means the velocity is the same for example it stays 5m/s throughout the journey.

Answer 5

Velocity is displacement/time, i.e. total displacement in specified time, when the velocity is uniform it have an acceleration is 0, i.e it is the condition where the body displaces equally in equal intervals of time.

Acceleration is the gain of velocity in one second (we can define like that for better understanding) i.e. is in uniform acceleration a constant gain of velocity is being take place.

Take a body moving with 10m/sec in constant velocity case it will have 10 m/sec velocity after any time as its acceleration is 0. If a body is moving with constant accelearation of 10 mt/sec say after 10 seconds the velocity is 100mt/sec

Answer 6

Velocity is the rate of change of displacement (position of a moving object), whereas the acceleration is the rate of change of velocity.
Both velocity and acceleration are vector quantities, i.e., they have magnitude and direction. The word 'uniform' signifies that they are constant both in magnitude and direction.

Answer 7

acceleration is the rate of change of speed......
i.e. the speed of an moving object varies frm time to time...
if the speed an object is 10 m/s nw. after one minute it is moving at a speed of 15 m/s. and after one more minute it becomes 20 m/s.
then the acceleration of that object = 5 metre/second square
and also it is in constant acceleration.........
since the speed of the object changes constantly as time advances........

constant velocity means an object is moving with constant 'speed' along a particular 'direction'........
when the term 'velocity' is mentioned, it refers not only to the speed but also to the direction.......for eg. an object moving at a velocity of 30km/hr towards 'north'........

thx....

Answer 8

In one, the acceleration is uniform (that is to say, constant in speed and direction), while in the other it is velocity that is uniform.

Answer 9

Uniform acceleration will make people think you have gained 'weight'.

Answer 10

One has a constant increase in velocity over time, the other doesn't.
