Velocity is a vector quantity that includes both magnitude (speed) and direction. Thus, velocity can be zero if there is no motion, but speed is the magnitude of velocity and cannot be negative. Speed is always a positive scalar quantity, so it cannot be zero if there is any motion at all.
What else can I help you with?
Can a particle in one dimensional with zero speed may have non zero velocity?
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.
What is the velocity if acceleration is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
How is velocity of zero different from an acceleration of zero?
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Can an object have a zero velocity and still accelerate?
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.
What is the slope of the body when it moves with uniform velocity?
When an object moves with uniform velocity, its slope is zero. This means the object is not accelerating and is moving at a constant speed in a straight line.
Can a particle in one dimensional with zero speed may have non zero velocity?
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.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
What is the velocity if acceleration is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
What is the acceleration if velocity is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.

When an object moves with uniform velocity, its slope is zero. This means the object is not accelerating and is moving at a constant speed in a straight line.
Why can velocity be zero?
Velocity can be zero if an object is at rest or not moving. This means that the object's speed and direction are not changing over time. In other words, the velocity of an object is zero when there is no movement or change in its position.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
Can an object have constant velocity and non-zero acceleration?
No, an object cannot have constant velocity and non-zero acceleration simultaneously. If an object has non-zero acceleration, it means its velocity is changing over time. Constant velocity implies a steady speed in a straight line with no change in direction or magnitude.
Can you have zero displacement and nonzero velocity?
i will give u an illustration, consider an object projected (thrown)with some initial vertical velocity from the ground such that it traces a open downward parabolicpath, in that path the vertical displacement of the body from the point of projection to the point where it strikes the ground is equal to zero,but it have some velocity.
Zero velocity what is it?
This means an object is at rest, at least relative to a certain frame of reference. For example, the object may be laying, not rolling, on the ground, and will remain at zero velocity until another force acts on it, or may be an object that was thrown straight up and is being slowed down and pulled back down by gravity, which will reach a velocity of 0 instantaneously and then begin to fall back down. This always happens at the object's maximum height.
