Question

in uniform circular motion does the the object moves in circular path ? Related:  Short Notes - Motion, Science, Class 9

Answer

As an object moves in a circle, it is constantly changing its direction. ... Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed.

Answer

Yes ,it move in a circular motion with change in velocity at every point and hence it is known as uniform circular motion

Answer

Yes object move in circular path with uniform speed that's why it is known as uniform circular motion means constant motion in circular path......

....

Answer

In Uniform Circular Motion, an object moves in a circular path.

In the study of motion, uniform circular motion refers to the movement of an object along a circular path at a constant speed. This type of motion is commonly seen in various real-life scenarios, such as the motion of a car around a roundabout or the orbit of planets around the sun.

Explanation:

Uniform circular motion involves two important components: the circular path and the constant speed. Let's understand each of them in detail:

1. Circular Path:
In uniform circular motion, the object moves along a circular path. This path is defined by a continuous curve with a fixed radius. The object continuously changes its direction, always facing towards the center of the circle. This is due to the presence of a centripetal force, which is responsible for keeping the object in its circular path.

2. Constant Speed:
In uniform circular motion, the object moves at a constant speed. This means that the magnitude of its velocity remains the same throughout the motion. However, the direction of the velocity constantly changes as the object moves around the circle. The velocity vector points tangent to the circle at any given point, always perpendicular to the radius.

Key Points:

- The object in uniform circular motion experiences a centripetal acceleration, directed towards the center of the circle. This acceleration is given by the equation a = v^2/r, where v is the speed of the object and r is the radius of the circle.
- The centripetal force required to maintain the object's circular path is provided by some external force, such as tension in a string, gravitational force, or friction.
- The period of the motion is the time taken for the object to complete one full revolution around the circle, while the frequency is the number of revolutions per unit time.
- The angular velocity, represented by the Greek letter omega (ω), is the rate at which the object rotates around the circle. It is given by the equation ω = 2π/T, where T is the period of the motion.

Conclusion:

In uniform circular motion, an object moves in a circular path with a constant speed. The object experiences centripetal acceleration and requires a centripetal force to maintain its circular path. Understanding uniform circular motion is essential in various fields, including physics, astronomy, and engineering. It helps us explain the behavior of objects moving in circular paths and provides a foundation for understanding more complex motions.
