Yes.
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
Yes, an object can have zero velocity and still be accelerating if its speed is changing in a direction other than its initial motion. For example, if an object is moving in a circle at a constant speed, its velocity may be zero at a certain point, but it is still accelerating due to the change in its direction.

When it has zero acceleration, it is moving at a constant velocity. If you change that velocity then it is accelerating. Remember velocity is a constant speed in a given direction. If the direction changes, then its velocity is changing hence it is accelerating. That's why if you go round in a circle , e.g. a fairground ride, your velocity is changing, hence you are accelerating, and so feel as though you are going to be thrown outwards. Remember Sir Isaac Newton's three laws of Universal Dynamics. A body/mass will remain stationary or in uniform motion, unless acted upon by a force. Force is directly proportional to body/mass and acceleration. To every force there is an equal and opposite force.
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".
Yes, a body can have zero velocity and still be accelerating if its speed is changing, either increasing or decreasing, over time. This is because acceleration is a measure of how the velocity of an object is changing, regardless of its current velocity.
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.
No, an accelerating object cannot have zero speed. Acceleration is the rate at which the speed of an object changes over time. If an object is accelerating, its speed is increasing or decreasing, but it cannot be zero.
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.
