What is the direction of acceleretion of a body in circular motion?

-- The acceleration is directed from the body to the center of the circle.
-- The velocity is tangent to the circle at the place where the body is.
That direction is also perpendicular to the acceleration at that moment.

∙ 11y agoThe velocity changes all the time (since the direction changes); the velocity is perpendicular to the radius.

What is the direction of a body when moving in circular path?
A body moving in a circular path has no fixed direction. Its direction keeps on changing with every step of its motion.
What causes circular motion?
Circular motion is due to the direction of a body/particle/object perpendicular to a radius of the circle drawn to the point of location of the object on 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.
Why a body moves in a circular motion?
A body will move in circular motion if there is a force to accelerate it towards the center.
Why is a particle in uniform circular motion not moving at a constant velocity?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.

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.
Why a body moves in a circular motion?
A body will move in circular motion if there is a force to accelerate it towards the center.
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?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
Circular motion occurs only near the earths surface?
False. A contra example; Triton has a circular motion about Neptune Newton's first law of motion: a body remains a rest or in uniform motion in a straight line unless acted upon by a force. If there is a centripetal force towards a point acting on a body that is moving then that body will have circular motion. The body and point do not have to be on earth.
Does a body in circular motion have kinetic energy?
No! <3
Define non uniform motion?
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
What is uniform circular motion?
Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
