well, its not the one about the fish.
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.
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.
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.
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, 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.
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.
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
Yes, an object moving at a constant speed can maintain a constant velocity if it is moving in a straight line without changing its direction. Velocity is a vector quantity that includes both speed and direction, so as long as the direction does not change, the object's velocity will remain constant.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
no
An object traveling at constant velocity cannot have acceleration because acceleration is the rate of change of velocity over time. If the velocity of an object is constant, there is no change in velocity and therefore no acceleration.
