Yes. Velocity is a quantity that has both magnitude and direction. Speed is the
magnitude of velocity. If speed is constant but the direction is changing, then the
velocity is changing. An example is a car turning a corner without slowing down.
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.
Motion without acceleration is when an object is moving at a constant speed in a straight line. In this scenario, the object's velocity remains constant and there is no change in its speed or direction.
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
no
No, an object cannot have constant speed and varying velocity at the same time. Velocity is a vector quantity that includes both speed and direction. If velocity is varying, then speed must also be changing as the object's direction changes.
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
Yes, for example, if it moves in a circle.
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
No, because constant velocity means constant speed and constant direction
Yes. An object moving in a straight line at constant speed has constant velocity.
Velocity can change even if speed is constant.
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
When the velocity of a moving object stays the same, it has a constant speed.
No, if an object's speed is constant, then it is not accelerating. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object's speed is constant, it means there is no change in velocity and therefore no acceleration.
