Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes. Imagine a ball on a rigid pole being swung around, and slowing down. It's tangential velocity is positive but it's tangential acceleration is negative
Is it possible for a body to move in a circle with constant speed constant linear velocity?
While your speed may be the same, your direction is constantly changing. So there is an angular acceleration. The force caused by this is called centripetal force, and it points towards the center of the circle. You can know this by feeling it, or by drawing a picture of the force system. Acceleration is broken up into normal and tangential components for rotation. The tangential is zero because you are moving at a constant speed, however the normal is not zero, and points to the center of the circle by definition.
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".

Is it possible to achieve a constant acceleration?
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
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.
Is it possible for a body to have an acceleration when moving with constant speed explain?
Yes, it's acceleration will be zero because the velocity isn't changing, but it has an acceleration. Think of it in terms of integration and derivation. Acceleration is the derivative of velocity, so if velocity is a constant number the acceleration must be zero.Generally if value of acceleration is "zero", we consider it to mean that there is NO acceleration. The question that was actually answered above was "Can acceleration be DEFINED fora body moving at constant speed?"It is possible for an object to be moving at a constant angular speed and yet have an effective acceleration in a tangential direction.===========================================Both of you guys are missing the most important point here, with the resultthat you have to twist your own arm almost to the point of dislocation in orderto state an answer.The essential underlying consideration is that, contrary to popular misconception,"acceleration" does not mean 'speeding up', or even 'changing speed'. It means"change in velocity", and "velocity" means "speed anddirection". If either speedor direction change, then that means there is 'acceleration'.The answer to the question is simple, and almost entirely non-technical. It is:"Yes, because 'acceleration' means change of either speed or direction. So, ifthe direction of the body's motion is changing, then the body has acceleration,even if its speed is constant."
Is it possible for a body to have acceleration when moving with constant veloctiy?
No, because acceleration is the rate of change of velocity.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.
Is it possible to differentiate acceleration with respect to time?
The variable obtained by dividing the acceleration by time is called "jerk".
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 an objects velocity to be perpendicular to the objects acceleration?
no
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
