Gravity
Definition
Gravity is a fundamental force that attracts objects with mass towards each other. It is responsible for phenomena such as planetary motion and keeping us grounded on Earth.
Analogy
Picture yourself jumping off a diving board into a pool. As you fall towards the water due to gravity, you experience an attractive pull towards it just like how objects with mass are attracted towards each other.
Related terms
Mass: A measure of the amount of matter in an object. It determines the strength of its gravitational attraction.
Gravitational Field: The region around a massive object where it exerts a force on other objects with mass.
Newton's Law of Universal Gravitation: Describes the gravitational force between two objects as directly proportional to their masses and inversely proportional to the square of their distance apart.

A 2 kg mass is attached to the end of a 1m long rope. The mass is swung in a vertical circle using the other end of the rope. If the speed of the mass at the lowest point in the circle is 5 m/s, what is the tension in the rope at that point? Assume that gravity is 10 m/s.
