A quantity that has magnitude as well as direction is called a vector. A directed line segment is a vector. The point A from where the vector AB starts is called its initial point, and the point B where it ends is called its terminal point. The distance between initial and terminal points of a vector is called Read more about Vector Algebra[…]
We know that hot water of milk, when kept at room temperature, cool drown gradually. But have you noticed that the rate at which hot milk cools down to a lukewarm state is lesser as compared to that required by a lukewarm milk to cool and attain the room temperature? Have you ever wondered why Read more about Newton’s Law of Cooling[…]

Sequence a₁, a₂, a₃ … the sequence {a₁ + a₂ + a₃ + … + an is called a series. A series is finite or infinite according as the number of terms added is finite or infinite. Example: List the first four terms of the sequence {an} = {n²}, starting with n = 1. {a₁, a₂, a₃, a₄} = Read more about Sequences and Series[…]
Have you ever noticed that once you fill a glass up to the brim with water, you can still add a few more drops till it spills out?

When any object is moved then its speed is changed which is called velocity while the change in velocity is acceleration. When it is changed continues then it is in accelerating condition which is called the rate of acceleration. It is equal to the ratio of change in velocity with respect to time between the given paths. The vector Read more about Acceleration Due to Gravity[…]

Potential energy is the ability of an object to store energy based on its position. For example, if you stretch a rubber band, to the farthest point energy will be stored in the object based on its position. The same thing happens when a wrecking ball is used to demolish buildings. The definition for gravitational Read more about Gravitational Potential Energy[…]
