No, because constant velocity means constant speed and constant direction
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
No. If the speed varies, the body accelerates, and velocity cannot be constant.
Yes, if you are going in a circle or otherwise changing direction.
Yes, if you are going in a circle or otherwise changing direction.
Yes, if you are going in a circle or otherwise changing direction.
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.
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.
The speed and direction of a moving body is called velocity. Velocity is a vector quantity that specifies both the speed of an object and the direction in which it is moving.
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
