Derive the relation between Angular Velocity and Linear Velocity
Derive the relation between Linear displacement and Angular Displacement
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 […]
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 […]
Linear and Angular motion – relationship equations
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 […]
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 […]
Here goes a set of Circular Motion Problems. This set contains Physics numerical problems on centripetal force and uniform circular motion for class 11. Solutions are also appended in this post for our students.
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 […]
Apparent weight of a moving car over a convex or concave bridge is the amount of Normal Reaction the car receives while traveling over the bridge. Here the system consists of the car, the bridge which is either convex or concave and the motion of the car along the curvature. So to start off we […]
In this post we will discuss how does an astronaut feel weightless in a nearby orbit and what is the secret behind this weightlessness in a satellite? To start with lets see how we feel this weight. If an object rests on a surface, its weight acts downwards on the surface. According to Newton’s third […]
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 […]
We will derive the equation for Kepler’s Third Law using the concept of the Period of Revolution and the equation of orbital velocity. In this process, the equation of the Time Period Of Revolution of the Earth satellite would be derived as well. We’ll also solve sample numerical problems here using this law. So let’s start!
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.
Today’s topic is Critical velocity in a vertical circular motion. Once we are done with its definition we will derive the Critical Velocity formula. Definition: The minimum velocity of an object at the highest point of the rotation while having a vertical circular motion, is called Critical Velocity. If the velocity of the object falls […]
Centripetal Force concepts & facts with examples and Washing machine: In this post, we will discuss the fundamental concepts of centripetal force & its real-life examples like how the centripetal force helps the Washing machine operation, etc. We’ll find out how concepts of centripetal force have been intelligently implemented in Washing machines to wash clothes. […]
In this post, we will focus on the definitions of circular motion and linear motion first which will show their basic differences as well. In addition to this, we’ll derive a couple of important relationships between the quantities of circular motion and linear motion. We will derive the following:a) Relationship between angular displacement and linear displacementb) […]
