Can an object have varying speed without varying velocity?

(d) When a body move in circular motion the acceleration is non zero (v^2/R) and we can also keep the speed constant, so it is possible.

Can an object have varying speeds if its velocity is constant?

Yes, an object can have varying velocity if its speed is constant. So if a car were traveling at a constant speed of 20 m/s in a circle, then the velocity would be varying (because the direction is changing) while the speed remains constant.

Can an object change speed without changing velocity?

If the velocity is constant, then it changes position at a constant rate. For constant velocity, there cannot be any acceleration (or change in acceleration, therefore). This means the object cannot change speed or direction.

Can an object have a varying speed if its velocity is constant if yes give examples?

You are going on a highway at a constant velocity 100 mi/hr east, and since the velocity already includes speed as a magnitude, the speed is also constant but has no direction. Therefore, in this case the magnitude of velocity which is speed is constant, but the velocity changes due to the change in direction.

What is varying speed?

Speed that changes from one state to another like increasing speed.

Can you move with constant velocity but not constant speed?

Is it possible to move with constant velocity but not constant speed? The answer to the first question is yes. Velocity means speed and direction, if the velocity is constant, then that means both speed and direction are constant.

How can an object have no change in speed and still have a change in velocity and acceleration?

Acceleration therefore occurs whenever an object changes direction- for example, a car driving around a roundabout is constantly accelerating even if its speed does not change.

How is it possible to accelerate without changing speed?

Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. If you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going.

Can an object have the same speed but different velocity?

Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. They represent objects that have different velocities only because they are moving in different directions.

Is it possible that a particle moving with a constant velocity may not have a constant speed?

You must be knowing that direction of the particle in circular motion is always in tangential direction. Hence its velocity is not constant as the direction is changing at each and every point of the circular path, though speed is constant.

How would it be possible for an object to be traveling with constant speed and still be accelerating?

The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.

Is it possible to accelerate and have a constant speed?

An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. Since it travels in a straight line, its direction does not change. Light travels at a constant speed, so its speed never changes, either.

Can an object have a varying speed if its velocity is constant?

No an object can not have a varying speed if its velocity is constant bcoz velocity is a vector quantity,which have magnitude as well as direction .speed is magnitude of velocity .so if speed is varying then velocity is also varying .so therefore it is not possible . YES, it can have varying velocity if its speed is constant.

Is it possible for velocity to change without changing speed?

Speed is magnitude of velocity… Since velocity is vector it has both magnitude as well as direction…change in any of magnitude or direction will change velocity…. However,Varying velocity without varying speed is ofcourse possible if we change the direction only keeping magnitude of velocity i.e. Speed constant or same.

Can the velocity of an object change in uniform circular motion?

The velocity of an object can be changed by: And in a uniform circular motion, the direction is not always the same, rather, it keeps changing. While the speed can remain the same. So in this way, the velocity can vary and the speed can be constant. But the vice versa is never possible.

Can the velocity of a particle change while maintaining a constant?

Yes, the velocity of a particle can change while maintaining a constant speed. No, speed cannot change if the velocity remains constant. If speed is changing then, by definition, its velocity is changing; it’s accelerating. Velocity is a vector quantity, meaning it requires magnitude (speed) and direction.
