The general kinematic equation representing such a motion is vuat v is final velocity after time t a is the acceleration and u is the initial velocity. If velocity is constant then Δ t Δ v 0 a 0 Therefore if a body has constant velocity it cannot have non-zero acceleration.

The ball experiences acceleration due to gravity at all time but at highest point its velocity becomes zero.
. If the velocity of a particle is zero at a given moment and if the particle is not accelerating the velocity will remain zero. A standing train is an example of zero velocity with zero acceleration. Let us consider an object moving in the forward direction.
The rate of change of angular velocity can independently be non-zero and total acceleration is the sum of these perpendicular vectors. Yes an object can have zero velocity and still be accelerating simultaneously. Yes an object can have have zero velocity and non-zero acceleration.
Since acceleration is the change in velocity over time there has to be a change in velocity for something to accelerate. In other words if something is accelerating it has to have a. But there are certain things in life where only definitions can not define another parameter but these parameters or things may be explained using certain logic.
When velocity is zero acceleration can be either zero or non zero. It could be either positive or negative. At terminal velocity the skydiver has non-zero velocity about 56ms or 200kmh but zero acceleration because their velocity is not.
When velocity is zero acceleration can be either zero or non zero. This happens when an object is at rest and when a force is applied on. An example would be a ball thrown upward.
At the highest point the velocity is zero and instantaneous acceleration is -98 ms2. However acceleration can also be non zero. Nonzero acceleration assuming it is constant.
Acceleration is the time rate of change of the velocity of a particle. For the most part velocity is not zero if an object is accelerating. Thus according to this definition if the velocity of the object is zero or constant then its acceleration will be zero.
Since the question states that average acceleration I cant think of an example that would satisfy the question. If the particle is accelerating the velocity will change from zero the. In any 1D motion when the velocity changes its direction to the opposite the velocity at this instance of time is zero while the acceleration is not.
Yes an object can have have zero velocity and non-zero acceleration. Consider a ball thrown upwards. We all know that acceleration is rate of change of velocity.
Now suddenly a force acts on it and tries to accelerate the object in the reversed direction. While observing the object you will find that the object will continue to move forward for some time and then stops instantly. Answer 1 of 2.
If the question would be Can you have a zero velocity and nonzero acceleration my answer would be yes. If the particle is accelerating the velocity will change from zero the. Object can have zero acceleration and non zero velocity at the same time when velocity is constant that is in uniform motion.
