Define uniform circular motion. An object of mass'm' is moving along a circle of radius r with increasing speed. Find the magnitude and direction of the net force acting on that object when the angular velocity is 'v' and angular acceleration is 'd'

Solution

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.
Here force =mv²/r
where acceleration=d= v²/r

Its direction is along the tangent, in outward direction.

Choose the correct statement:

Statement 1: Unbalanced forces can change the direction of motion.

Statement 2: A balanced force is required to accelerate the motion.

Statement 3: An object moves with a uniform velocity when balanced forces are acting on it and there is no net force acting on it.

Statement 4: Balanced force cannot start a motion.
