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.

No, the definition of acceleration is the increase change in velocity over time. An acceleration can also be a decrease in velocity over time. Constant velocity refers to an object that maintains the same velocity as time progresses. If the object has an acceleration, its velocity will not remain constant.

In the case of rotational velocity there is a constant internal acceleration that has the magnitude v2/r

No. Since the direction changes, so will the velocity.

Can uniform velocity appear in circular motion?

No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.


Can an object be accelerated if it is moving with constant speed if yes explain giving examples?

Yes, it can. Perhaps the simplest example is when an object moves at constant speed, in a circle. In this case, the speed doesn't change; the velocity does.


What happens to an object when it reaches terminal velocity?

If someone is skydiving, the terminal velocity would be the greatest velocity reached by the falling person until they open their parachute. So in that case, the effect would be slowing down because of the parachute. The effect may vary from different cases.


Example of something that undergoes acceleration while moving at constant speed?

Any object moving in a circle (as in a centrifuge, or a planet in an orbit) is accelerating. More generally, any object that moves in a curve is accelerating (such as a car moving in a curve on the road).


What is the differnce between velocity and speed?

Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously

When you go around a curve is your velocity changing?

Yes; although speed ( a scalar quantity) may be constant the velocity ( a vector with quantity and direction) is changing because the direction is changing

Why are you accelerating when you go around a corner at a constant speed?

Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.


A merry-go-round horse moves at a constant speed but at a changing?

. . . velocity, because one of the components of velocityis the direction of the speed.


What is an velocity?

Velocity is the measure of increasing and decreasing speed. For example... on a velocity graph, if the object being measured is gradually getting faster the line will go up. If it is getting slower, it will go down, if it is staying at a constant speed, the line will be straight

Does a bicycle have to feel a force in the direction of its motion to go around a curve?

yes


What might happen if you understeer going around a curve?

You may go off the road.


Driving around a curve what way the car want to go?

A curve to the left, the vehicle would go to the right with no steering. A curve to the right, the vehicle would go left with no steering. Because any object in motion will continue to go straight unless another force takes it in another direction.


How far does a car go if it goes at a constant velocity of 15 meters per second for 4 seconds?

distance = velocity x time = 15 m/s x 4 s = 60 m
