 # How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation c.

in both magnitude and direction

explanation:

c.

in both magnitude and direction explanation: As the direction of the centripetal acceleration is always towards inward, towards the center of curvature of the circular path. So the option c is correct that the centripetal acceleration is directed radially inward.

Explanation: C. in both magnitude and direction

Explanation:

Circular motion is the movement of a body rotating around an axis along a circular path of constant radius. This movement can be uniform, if the speed of rotation is constant, or varied, if its speed changes over time. When an object moves in a circular motion, the speed is constant in magnitude and direction.

The circular movement occurs when a force of constant modulus is applied in a direction perpendicular to the speed of a piece of furniture, so that the modulus of this velocity remains constant, changing only its direction and its direction. The force applied in this case is called the centripetal force. C. The centripetal acceleration is directed radially inward

Explanation:

Centripetal in the real sense of it means towards the centre. Any object undergoing a circular motion which is uniform (uniform circular motion) has a centripetal acceleration and that acceleration is directed radially inwards. The acceleration has a magnitude that is equal to the square of the speed of the object along the curve, divided by the distance from the center of the circle to the object in motion.

Mathematically it can be expressed as; = Where v is the speed/velocity of the moving object and r is the distance of the object from the centre of the circle. 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. ... The net force acting upon such an object is directed towards the center of the circle. In both magnitude and direction since acceleration is a vector quantity Motion because the motion is the range Uniform circular motion is when an object travels in a circular path at a constant speed.

Direction of the velocity is constant
Direction of the acceleration is inward.  ### Other questions on the subject: Physics Physics, 22.06.2019 03:00, jdkrisdaimcc11
