Gravitation

Acceleration due to gravity – how it changes with height and depth

Gravitational Attraction of the earth and Acceleration due to gravity In this post we will work on the expression of Acceleration due to gravity on the earth’s surface. We will take help of Newton’s Law of Gravitation as well as Newton’s second Law of Motion. We will also explore how height or depth from the

Gravitation: Why does a stone fall towards the earth but the opposite is not observed?

Gravitation and a Falling Stone As said by this law of universal gravitation every object in this universe is attracting every other object towards it. This force of gravitational attraction between any two objects in the universe is inversely proportional to the square of the distance between the objects. This force is again directly proportional

Sir Isaac Newton and the Universal Law of Gravitation

Universal Law of Gravitation Have you heard of the story about Sir Isaac Newton and a falling apple which was pulled toward earth by the force of gravity? An apparently unimportant event led to Newton’s formation of a fundamental law of nature (law of universal gravitation) which involves gravitational forces. We’ll discuss on this law

What will happen to a ball thrown vertically upwards?

Motion of a ball thrown vertically upwards You must have seen someone throwing a ball vertically upwards or probably you have thrown it yourself. Yes, the ball goes up for a while and then stops and starts to come down and touches the ground with a bang if you can’t catch it. Let’s discuss the phases
