Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
What else can I help you with?
Why achanging velocity cannot maintaining constant speed?
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.
Can an object have a constant speed and a varying velocity?
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.
How can a vehicle at the same time have a constant speed but changing velocity?
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
Can an object have zero velocity and nonzero acceleration?
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
Can a body have constant velocity when it has constant speed?
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
Can a body have constant velocity but changing speed?
No, not at all possible. But constant speed with changing velocity is possible.
Why achanging velocity cannot maintaining constant speed?
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.
Can an object have a constant speed and a varying velocity?
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.
If you are traveling around a curve at a constant speed of 30 km is the veiocity change?
Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.
Is a person running in a circular track at 7mph an example of constant velocity at zero acceleration and if so why?
Yes, a person running in a circular track at a constant speed of 7mph is an example of constant velocity and zero acceleration. While the person is changing direction, their speed remains constant, resulting in a steady velocity. Acceleration would only occur if there were a change in speed or direction.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
Can an objeact have constant speed and but variable velocity?
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Can a velocity of a body change its speed is constant?
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.
Can an object have a varying speed it its velocity is constant?
Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.
Can a body have constant velocity and changing speed?
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.
