If the displacement of a body is proportional to square of time will the body be moving with uniform velocity or uniform acceleration?

Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality.
Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt
Since, velocity depends on time ,the body is not moving with uniform velocity....
Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k
As the acceleration is independent of time , the body is moving with uniform acceleration..

Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
For uniform circular motion the quantity that does not remain constant is?
this my sound rather daft but this is a bit of a trick question, the speed is the same so straight away you would think the acceleration is constant right....???? Wrong the displacement of the object is changing (displacement is the distance being travelled with a direction, a vector quantity.) as the displacement is changing so is the velocity, as velocity is displacement/time. as the velocity is changing so is the acceleration because acceleration is then change in velocity divided by time.
What is the difference between uniform and variable velocity?
Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration. Lauren "Physics above all!"
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
What is the acceleration of vehicle moving with uniform velocity?
It has zero acceleration!!
Determine the displacement of a plane that experiences uniform acceleration from 59 ms to 78 ms in 12 s?
use a uniform acceleration equation, Δx = ½ (Vi + Vf) Δt where displacement = 1/2 (initial velocity + final velocity) time displacement = 1/2 (59 m/s + 78 m/s) * 12s displacement = 822 m

Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
When a cars velocity is uniform what it is acceleration?
Acceleration is change of velocity divided by time; so if the velocity doesn't change, acceleration is zero.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
What is the acceleration of vehicle moving with uniform velocity?
It has zero acceleration!!
How the velocity uniform?
"Uniform velocity" means zero acceleration, that is, constant speed in a straight line.rate of change of velocity is zero
What is the velocity equation?
If the velocity is constant then it is enough to use the equation, s = vt. S- the displacement, t - time elapsed and v the uniform or constant velocity. If velocity changes, then acceleration is there in action. Hence the final velocity after time t will be given as v = u + at.
