The direction of acceleration of a body in circular motion is towards the center of the circle. This acceleration is called centripetal acceleration, and it is responsible for changing the direction of the body's velocity to keep it moving in a circular path.

What is the direction of a body when moving in circular path?
The direction of a body moving in a circular path is constantly changing due to centripetal acceleration. At any point in the circle, the body is moving tangent to the circle, while the acceleration is directed towards the center of the circle.
Uniform and non-uniform motion?
if a body performs motion with constant speed along a circular path,its motion is called uniform circular motion. here,note that speed remains constant , not velocity. direction of velocity of a body in uniform circular motion, is different at each point on the circular path. consider a body performing uniform circular motion along the circle of radius'r' in anticlock wise direction. when this object is on points a,b,c,d and e, directions of its velocity are shown.v1=v2=v3=...v5=v v=distance travelled ----------------------- time =length of circular path ---------------------------- time v=circumference ----------------- time =2pier ------- t here v is also known as linear speed of the body performing uniform circular motion.
What causes circular motion?
Circular motion is caused by a centripetal force acting on an object that keeps it moving in a curved path. This force pulls the object towards the center of the circular path, preventing it from moving in a straight line. When this force is balanced with the object's inertia, it can maintain a constant speed and direction in its circular motion.
Which direction is the centripatel force acting for a body n uniform circular motion?
The centripetal force for a body in uniform circular motion is directed towards the center of the circle around which the body is rotating. It is responsible for keeping the body moving in a curved path rather than in a straight line.
Can centripetal force work on the rotating body?
Yes, centripetal force is required to keep a rotating body moving in a circular path. It acts towards the center of the circular motion, causing the body to constantly change direction while moving in a circular path.
What is circular motion?
Circular Motion -a motion along a circular path or the motion of an object in a circular Example -blades of a ceiling fan when the fan is switched on. or The motion of body along the circular path is called circular motion

What should be the angle between the direction o foce and the direction of motion of a body so that the work done is zero?
Work is zero when the force is perpendicular to the direction of motion, as it is, for example, in a circular gravitational orbit.

Uniform linear motion vs uniform circular motion?
Uniform linear motion is when an object moves in a straight line at a constant speed, while uniform circular motion is when an object moves in a circle at a constant speed. In uniform linear motion, the velocity remains constant in both magnitude and direction, whereas in uniform circular motion, the object's velocity remains constant in magnitude but changes direction constantly.
Why is the motion of a particle along a circular path with a uniform speed said to be an accelerated motion?
To accelerate a body one must change its velocity or direction at an instantaneous moment. Since in a the velocity is uniform the direction at every point on the circular path is different. Thus making it accelerated.
Why is a particle in uniform circular motion not moving at a constant velocity?
In uniform circular motion, the particle's direction is constantly changing even though its speed may remain constant. Since velocity is a vector quantity that includes both magnitude and direction, the changing direction means that the velocity is also changing. Therefore, the particle is not moving at a constant velocity.
Why a body in uniform circular motion experiences a force?
A body in uniform circular motion experiences a centripetal force directed towards the center of the circle, necessary to keep it moving in a curved path instead of moving in a straight line. This force is required to constantly change the direction of the body's velocity, causing it to accelerate towards the center of the circle.
What is the work done by a body moving along a circular path?
The work done by a body moving along a circular path is zero if the force is perpendicular to the direction of motion, such as in the case of centripetal force. This is because the displacement is perpendicular to the force. If there is a component of the force in the direction of the motion, work is done, calculated as the dot product of the force and displacement vectors.
