An object is moving in a uniform circular motion. It is released while moving in a circular motion. It will

1. Fly out tangentially to the circular path.
2. It will fly out radially to the circular path
3. It will continue to move in circle
4. It will move towards the center of the circle.

Which statement is true about an object that is moving in a uniform circular motion?

1. The speed of the object varies.
2. The net force on the object is directed towards the center of the circular path.
3. The net force on the object is directed away from the center of the circular path.
4. The velocity of the object is constant

What is the relation between radius, velocity, and time period?

When is an object said to be accelerated?
A student writes the following points:

1. When there is change in speed.
2. When there is change in direction.
3. When there is change in the magnitude of the velocity.

Identify the correct option/s.

1. Option a and b
2. Option b and c
3. Option a and c
4. Option a, b and c

In a motion the magnitude of the velocity is constant, but the direction is not constant, and the force is acting towards the center. Identify the motion being talked about.
