Uniform Circular Motion Class 10 ICSE Physics Notes Chapter-1 Force

Uniform Circular Motion: Movement of an object along a circular path at a constant speed, where the velocity is constantly changing direction

Speed is Uniform But Velocity is Non Uniform

At any point the direction of motion is along the tangent drawn at the point of circular path.

Difference between Uniform Circular Motion and Uniform Linear Motion

Uniform linear motion involves constant speed and direction along a straight path,
uniform circular motion involves constant speed but changing direction along a circular path.

A force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

Examples of Centripetal Force

A Merry-go-round.
Turning in a car
Planet Earth.
Electron revolve around Nucleus
Moon moves around the Sun

Centrifugal Force

a force, assumed by observer which appears to act on a body moving in a circular path and is directed away from the center around which the body is moving.

Example of Centrifugal Force

Weight of an object at the poles and on the equator.
A bike making a turn.
Vehicle driving around a curve.
Equatorial railway.

Example of a Merry-go-Round

When a kid sits in a merry-go-round and it starts to rotate, the force that pulls the kid toward is the centrifugal force. This force works towards the outward and pulls the object towards the outward too

Differences Between Centripetal Force and Centrifugal Force

Centripetal Force	Centrifugal Force
Its direction is towards the center of curvature.	Its direction is away from the center of curvature.
It is observed from the inertial frame of the reference.	It is observed from the non-inertial frame of reference.
Its force is towards the axis of rotation.	Its force is outward of the axis of rotation.
It is considered a real force.	It is considered a pseudo-force.
