When the body is in simple hermonic motion
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..
As long as it has a non-zero velocity, it will have a non-zero momentum.
as direction is changing
When a body moves with uniform, its acceleration is is constant if v(m/s) t(s) a(m/s2) 4 1 0 8 2 4 12 3 4 16 4 4 (8-4/1)=4 12-8/1=4 hence acceleration is constant.

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.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
As long as it has a non-zero velocity, it will have a non-zero momentum.
as direction is changing
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
When a body moves with uniform, its acceleration is is constant if v(m/s) t(s) a(m/s2) 4 1 0 8 2 4 12 3 4 16 4 4 (8-4/1)=4 12-8/1=4 hence acceleration is constant.
A body moving with uniform velocity is in equilibrium when it moves with uniform velocity as no acceleration i.e. no net force acts on the body.The sum of all forces must be zero in this case. (To avoid rotation, the sum of all torques must also be zero).
uniform acceleration mean that the acceleration doesn't change over the course of time of the time considered for a certain
Uniform acceleration means that the acceleration doesn't change over the course of time (of the time considered for a certain problem, at least).
