No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
No, not at all possible. But constant speed with changing velocity is possible.
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.
Yes, but only for an instant.
No, constant speed implies that the body is moving at a consistent rate, while variable velocity means the direction of motion is changing. It is not possible for a body to have both constant speed and variable velocity simultaneously.
velocity means speed of an object and in a definite direction.That shows velocity changes with speed
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
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.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
In common speech, velocity means speed, they are the same thing.
