Characteristics of circular motion
What are the characteristics of circular motion class 12?
The object follows a circular path. The object passes through the initial point repeatedly. The motion can be periodic. The object always moves in a straight line.
What are the two conditions for circular motion?
Circular motion requires a net inward or “centripetal” force. Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.
What are the components of circular motion?
There are three mathematical quantities that will be of primary interest to us as we analyze the motion of objects in circles. These three quantities are speed, acceleration and force. The speed of an object moving in a circle is given by the following equation.
What is the essential characteristic in physics for uniform circular motion?
An essential characteristic of uniform circular motion is that the direction of motion changes continuously with time, accelerated. Centripetal force brings about uniform circular motion.
What are the three principles of circular motion?

|---|---|
| What are the three principles of circular motion? | 1. Circular motion requires centripetal force. 2. The larger the centripetal force, the faster an object travels in a circle of a given size. 3. At a given speed, the larger the centripetal force, the smaller the circle. |
What are the types of circular motion?
There are two types of circular motion mentioned below: Uniform circular motion. Non-uniform circular motion.
Which of the following are always true for circular motion?
Acceleration in uniform motion is directed towards center and hence direction of acceleration is always changing.
What is circular motion formula?
The instantaneous acceleration in a uniform circular motion is given by. a = v2/R. v is the velocity of the object. R is the radius of the circle. The direction is perpendicular to velocity and directed inwards along the radius.
What is meant by circular motion?
In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
Which of the following is an example of circular motion?
Circular motion is a motion in which object moves in a circle with respect to a fixed point. Here, the satellite orbiting around the Earth is an example of a circular motion.
Which statement is true about an object that is moving in a circular motion?
The direction of the object’s velocity is constant.
What can you say about objects moving in circular motion?
The force causing circular motion is directed toward the center of the circle. The speed of the object does not change, but the direction of movement is constantly changing.
Why do objects move in circular motion?
While an object moves due to velocity, or its speed in a certain direction, centripetal force is the force that keeps the object moving in a circular path. It does this by pulling an object toward the center of a circle.
What keeps the object moving in circular path?
A centripetal force is a net force that acts on an object to keep it moving along a circular path.
