I'm trying to give you a simple example. Which hope will be able to make you understand that thing. We read physics in our language. So I can make some mistakes to write that in English... But I hope I won't be mistaken. By the way here it is...
Suppose, There is a simple oscillator what is moving under the angles of 4 degrees. When it is in his height position then we know that it stops for a moment and then comes back to the equilibrium position. So in the height position it's velocity is 0 m/s. (cause it stops.) Suppose it's 1st velocity or the velocity in the equilibrium position is "v" and in that position the last velocity is 0. so we can calculate it's acceleration like that
a = (last velocity-1st velocity)/time
so a = (0-u)/t = - u/t, what is the maximum acceleration of a this body, (-) sign means the acceleration is gonna go down.
But when it is coming back to the equilibrium position, it's velocity goes up.. And in the equilibrium position it's velocity is maximum. Then the velocity decreases again. so in the equilibrium position the velocity is maximum, in the equilibrium position which is "v". so it's acceleration will be
a= v-v/t = 0/t = 0, that means the acceleration is zero when the velocity is maximum...
That means the acceleration of a body can be zero when the velocity is maximum and the velocity can be zero when the acceleration is maximum.
[Note: Always remember, to start to calculate from the equilibrium position. Because the oscillation starts from the equilibrium position. And what I said is the most simple statement. It can also be described by the equations of the a simple harmonic oscillations]

What else can I help you with?
Is it possible for a body to have acceleration when moving constant speed and constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Is it possible for a body to have the same acceleration and velocity?
The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
Can a body have accerlation butb still have zero velocity?
Yes, it is possible. When a body thrown upward (from the surface of Earth or any other planet but with velocity small enough not to overcome the gravity) and reaches its maximum elevation its velocity is zero but the acceleration is g (due to gravity).
Is it possible for a body to have acceleration when moving with constant veloctiy?
No, because acceleration is the rate of change of velocity.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Is it possible for a body to have its velocity and acceleration pointing in opposite directions?
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.
Is it possible of a body to have its velocity and acceleration pointing in opposite direction plot a velocity-time graph if yes?
Yes, it is possible for a body's velocity and acceleration to be in opposite directions. This would result in the body's velocity decreasing over time while its acceleration remains negative. On a velocity-time graph, this situation would be represented by a curve that starts with a positive velocity and decreases over time.
Is it possible for body to have its velocity and acceleration pointing in opposite directions?
Sure. Anything that's slowing down has velocity and acceleration in opposite directions. -- A ball tossed up in the air has upward velocity and downward acceleration. -- A car stopping for a red light has forward velocity and backward acceleration.
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
When a body has constnat velocity what is the acceleration?
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
Can a body have no velocity and still have acceleration?
Yes, it is possible for a body to have zero velocity but still have acceleration. This occurs when the body is changing its direction of motion, even though its speed remains constant. The acceleration in this case is due to the change in direction, not speed.
