Uniform Circular Motion

Uniform circular motion

It is the motion I a circular path at a constant speed

Centripetal acceleration

It is the acceleration which is directed towards the center of the circular path

increases; increases; decreases

Centripetal acceleration (decreases or increases) as the tangential velocity (decreases or increases) or as the radius (decreases or increases)

Accelerate

From Newton’s law of acceleration, an object will (not accelerate or accelerate) if a net force acts on it.

Centripetal Force

It is defined as an object is traversing on a circular path which is also a center-seeking force that keeps an object on its path

Tangential

Without the centripetal force, the object will tend to move ______ to the circular path in a straight path

Torque

It is the ability of a force to rotate an object.

Force; lever arm

The torque is a product of the _____ and ______

Lever arm

IfIt is the perpendicular distance from the axis of rotation to the line along which the force acts

No torque

If the force acts towards the axis of rotation, there will be (a torque or no torque)

Positive

A torque that causes a counterclockwise rotation is assigned to be (positive or negative)

Negative

A torque that causes a clockwise rotation is assigned to be (positive or negative)

Balanced

In a stationary object, all the forces acting on it are (balanced or unbalanced) and so as the torque
