Can we detect dark matter or has anyone detected it till now? Let find out. Also subscribe the blog for email notifications. What is Dark Matter? Dark matter is a type of matter. Dark matter is called Dark because it does not appear to interact with electromagnetic field, which means it doesn't absorbs, reflect or emit electromagnetic radiations, and is therefore difficult to detect.

What Happens: When an object is freely falling

Let us first understand what gravity is. Gavity also known as gravitation, is a phenomenon (not a force) of attraction of all the things that have mass-energy like planets, galaxies and light towards one another. What happens: when an object is freely Falling? Don't get confuse between gravity and Gravitational Force. They are separate terms. Gravity is a natural phenomenon. Whereas, Gravitational force is a force that is a measure of attraction. Gravity is the phenomena or cause of, why we are able to stand. Whereas gravitational force is responsible for our weight. If you go to moon then your weight becomes 1/6th of  the weight on earth. Gravity is the reason, why planets revolve around sun., and moons revolve around planets. It is the phenomena, which plays an important role in galaxy formation. Most of the galaxies have a black hole as their centre. Black hole have very large gravitational effect. Now from Newton's laws of motion , we know that ac...
