Centripetal force sources – sources of centripetal forces

In this post, you will find a List of Common circular motions and the sources of centripetal force (in tabular format) for each of these motions. Any force can be a centripetal force. Centripetal force is an umbrella term given to any force that is acting perpendicular to the motion of an object and thus […]

Centripetal And Centrifugal Force

In this post, we will define centripetal force and centrifugal force, and find out how these two differ from each other. We will also go through some examples of these forces. In this discussion, we will also understand what centripetal acceleration is. Defining Centripetal Force Centripetal Force (Fc) is the force that sustains the circular […]

Deriving the equation of Centripetal acceleration (using trigonometry)

In this post, we will derive the equation of centripetal acceleration using trigonometry. In a different post, we have done the derivation of the equation of centripetal acceleration using differential calculus. How to derive the equation of Centripetal acceleration (using trigonometry) In the above figure (figure 1), a particle is moving in a circle with […]

Derive formulas of centripetal force & centripetal acceleration

In this post, we will derive formulas of centripetal acceleration & centripetal force while we discuss the uniform circular motion. Uniform circular motion & its acceleration An object moving with uniform circular motion moves along a circular path of fixed radius at a constant speed. Since the direction of motion of the object is constantly […]

Law of Conservation of Angular Momentum – statement and derivation

In this post, we will study the Law of Conservation of Angular Momentum with its statement and derivation. State the Law of Conservation of Angular Momentum The Law of Conservation of Angular Momentum states that angular momentum remains constant if the net external torque applied on a system is zero. So, when net external torque […]

Angular Momentum

When an object moves with an angular speed ω along the circumference of a circular path of radius r, then we say that it has angular momentum. Angular momentum is the rotational equivalent of linear momentum and is defined as the moment of Linear momentum. It depends on 2 quantities, one is rotational inertia or […]

Orbital Velocity derivation & concepts for class 11 | How to derive the orbital velocity equation?

Orbital Velocity of a satellite is the minimum velocity it has to maintain to continue its circular motion in its orbit or in other words it is the minimum velocity of the object in circular motion that generates enough centripetal force to keep it in the circular orbit of given radius. We will discuss this in details as well as we will focus on the derivation of Orbital Velocity formula.
