FAQs on Fun Video: Uniform Circular Motion Video Lecture - Class 9

1. What is uniform circular motion?

Ans. Uniform circular motion refers to the movement of an object along a circular path at a constant speed. In this type of motion, the object's velocity is always tangent to the circle and its magnitude remains constant.

2. How is uniform circular motion different from non-uniform circular motion?

Ans. In uniform circular motion, the object moves at a constant speed along a circular path. On the other hand, non-uniform circular motion involves a varying speed along the circular path. In non-uniform circular motion, the object's velocity vector constantly changes its magnitude and direction.

3. What is the centripetal force in uniform circular motion?

Ans. The centripetal force in uniform circular motion is the force that acts towards the center of the circular path, keeping the object moving along the path. It is responsible for continuously changing the object's direction without changing its speed. The centripetal force is always perpendicular to the object's velocity vector.

4. How is centripetal force related to uniform circular motion?

Ans. Centripetal force is crucial for maintaining an object's motion in a circular path. Without a centripetal force, the object would move in a straight line tangent to the circular path. The magnitude of the centripetal force can be calculated using the formula F = (mv^2) / r, where F is the centripetal force, m is the mass of the object, v is its speed, and r is the radius of the circular path.

5. Can an object in uniform circular motion experience a change in its speed?

Ans. No, an object in uniform circular motion cannot experience a change in its speed. In uniform circular motion, the speed of the object remains constant throughout the motion. However, it is important to note that the object's velocity is constantly changing as it continuously changes direction due to the centripetal force acting on it.
