Which of the following stays in equilibrium even after being slightly displaced?

Kinematics topics include: Centripetal force, energy and work. Kinematics is a branch of physics that studies the motion of objects without considering the forces that cause them to move. It includes concepts like distance, speed, and acceleration, and how those values change over time.  The word "kinematics" comes from the Greek word kinesis, which means "motion". It's related to other English words like "cinema" and "kinesiology".  Kinematics considers concepts like: Velocity: The displacement of an object divided by the time it takes.

The word "kinematics" comes from the Greek word kinesis, which means "motion". It's related to other English words like "cinema" and "kinesiology". 

Kinematics considers concepts like:
Velocity: The displacement of an object divided by the time it takes. Velocity is a vector quantity, which means it has both magnitude and direction.
Acceleration: The rate of change of velocity. Acceleration can be caused by a change in the magnitude or direction of velocity.
Uniform circular motion: When a body travels in a circle at a constant speed. The body's distance from the axis of rotation remains constant.
