Yes, for example, if it moves in a circle.
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, an object can have a constant speed but varying velocity if it changes direction while moving at that speed. Velocity includes both speed and direction, so if an object is moving in a straight line at a constant speed but changing direction, then its velocity is constantly changing even though its speed remains the same.
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.
When the velocity of a moving object stays the same, it has a constant speed.
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.
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.
