Thomas Edison was born on Thursday February the 11th, 1847 in the town of Milan, America. When Thomas was seven his teacher finally lost his patience…

A magnetic field is generated when electric charge carriers such as electrons move through space or within an electrical conductor. Magnetic field exists; how does it…

Primary purpose of this lecture is to present on Diffusive Shock Acceleration. Inhomogeneities of the magnetized plasma flow lead to energy changes of energetic charged particles due…

This lecture briefly describe on Newton’s Laws of Motion. First Law: Law of Inertia. An object at rest (v=0) remains at rest AND an object at constant velocity…

This lecture introduce on Units of Acceleration. Since acceleration is a velocity divided by a time, its units are a distance unit divided by two time units. This…

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…
