Physics

To simplify things as much as possible, we will first consider one-dimensional motion (motion along a straight line) of particles (points that can’t spin, rotate,…

In uniform circular motion, although the speed is constant, there is an acceleration because the direction of the velocity vector is always changing.  The acceleration…

Major purpose of this lecture is to present on Angular Velocity. The angular velocity is defined as the rate of change of angular displacement and is a…

In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. Consider a ball on a roulette wheel. It moves…

The aim of this lecture is to present on Projectile Motion. A projectile is an object that moves in two dimensions under the influence of only gravity. Projectile…

Prime purpose of this lecture is to present on How to Calculate Speed.  The speed of an object is how fast or slow it’s moving. You…

Basic purpose of this lecture is to present on How to Calculate Acceleration. Acceleration is the rate of change of velocity of an object. where a…

General purpose of this lecture is to present on Speed and Acceleration. It is a tutorial study based lecture. Acceleration is the rate at which velocity…

The measure of energy given to the charge flowing in a circuit. The greater the voltage, the greater the force or “pressure” that drives the charge…

Friction is the force that two surfaces exert on each other when they rub against each other. Some Causes of Friction are: the strength of the…

Friction is a Force that always pushes against an object when it touches another object. When two things are in contact with each other, there will…

A force is an influence on a system or object which, acting alone, will cause the motion of the system or object to change. If…
