Why are your velocity changes when you ride a ferris wheel even if the wheel turns at a constant speed?
A ferris wheel turning at a constant speed has no change in speed. But velocity is speed with a direction vector attached to it. Speed with a direction component is velocity. In this case, the distance per unit of time (speed) that something is traveling is constant, but the direction it is traveling is constantly changing because that something is moving in an arc (or circle). It's a ferris wheel, and anything on it has its velocity changing. Velocity is changing every second because the direction it is moving is changing. Any change in the velocity of an object will require that the object be accelerated. Even if its speed is constant, it will experience acceleration to change "just" the direction it is traveling. It's the same with an object in orbit. The object will be cruising along at a constant speed, but its velocity will be constantly changing. This is because the direction the object is moving is changing because it is being accelerated constantly to get it to move in an arc. The object was put in orbit, and it was accelerated into that orbit. Now, the object is being acted on constantly by gravity. The gravity is pulling the object back to earth, but if we look at where it is going at any instant of time, it is moving on a tangent to its path of travel. It moves a tiny bit on that tangent, and gravity pulls it "in" just a tiny bit, and that makes it path an arc. A little on the tangent, and a little "in" toward earth. A little more on the "new" tangent path, and a little "in" toward earth. A little more along the new tangent path, and a little more in toward earth. A smooth arc - a circle. The object in orbit is constantly being accelerated toward earth, and this acceleration constantly changes its velocity (but not its speed), and it moves in that circular orbit.
What else can I help you with?
Can you have constant speed but change in velocity?
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
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.
Why the speed of an object is constant while the velocity is not?
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.
Does velocity of an object remain constant in uniform circular motion?
No, the velocity of an object in uniform circular motion is not constant because although the speed may remain constant, the direction of the velocity continuously changes as the object moves along the circular path. This change in direction indicates a change in velocity, known as acceleration.
When you run around a track at 5 km h your velocity is constant?
Yes, if you run around a track at a constant speed of 5 km/h, your velocity is constant because velocity includes both speed and direction. As long as you maintain this speed and direction, your velocity remains constant.
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 you have constant speed but change in velocity?
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
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.

Yes, if you run around a track at a constant speed of 5 km/h, your velocity is constant because velocity includes both speed and direction. As long as you maintain this speed and direction, your velocity remains constant.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
Can an object have a constant speed and the varying velocity at the same time explain?
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.
' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
