Does a body moving in a circular path with constant speed has variable acceleration?

The answer is c. kinetic energy. When a body is moving in a circular motion with constant speed, the direction of it continuously changes and hence velocity(v), momentum(p), and acceleration change because they are vectors and their direction changes. only as kinetic energy is a scalar, it remains constant.

Can a body moving in circular path have constant velocity explain?

As mentioned earlier in Lesson 1, an object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction. It is accelerating because the direction of the velocity vector is changing.

Can a body have a constant speed with variable velocity?

Yes, a body has constant speed as well as variable velocity. Consider an example: A particle moving in a circular path with a uniform circular motion.

Can an object can move in a circle at a constant speed and still have a changing velocity?

An object moving in a circular orbit at a constant speed has a changing velocity. This is because velocity is a vector quantity that depends on speed and direction. The object in orbit is accelerating, even though its speed remains constant, because its velocity is changing.

When an object is moving with constant speed in a circle?

When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Its velocity is changing not because the magnitude of the velocity is changing but because its direction is. This constantly changing velocity means that the object is accelerating (centripetal acceleration).

Can a body have a constant speed while having constant velocity at the same time give or show example?

Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time. For example, consider a vehicle moving with a constant speed on a circular path.

Is it possible for a body to have constant speed and velocity?

If yes, give one example. Yes, it is possible for a body to have constant speed as well as variable velocity. A body moving on a circular path with constant speed that is undergoing a uniform circular motion has variable velocity. The direction of velocity changes each moment and hence the velocity is not constant.

Why is velocity not constant in a circular path?

To maintain a circular path, though, its direction must be constantly changing. Since a change in either speed OR direction means a change in velocity, the object’s velocity is not constant. Why is it useful to define velocity that way?

Is the speed of a moving body uniform in a circular?

Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time. One simple example is what we call Uniform Circular Motion . For example, consider a vehicle moving with a constant speed on a circular path.

What is the instantaneous velocity in a circular motion?

So, the instantaneous velocity in circular motion (uniform or not) swings around 360 degrees each time the object completes a circuit, The speed is constant. The velocity is continually changing.
