## What is speed in physics? (Definition, Formula, and Examples)

Concept of speed is one of the first concepts when we start studying physics. The concept of speed is discussed under kinematics. In this article, we will learn about the concept of speed, its formula, unit along with some examples. Let us first … Read more

## Non-Contact Force – Definition, Types, and Examples

As we already know, force is the push or pull that an object feels when it interacts with another object. This push or pull causes the object to change its state, either from rest or from moving in a straight line. Force can … Read more

## Centripetal Force Vs. Centrifugal Force

Ever swirled a stone at the end of a rope or seen a roller coaster performing a 360-degree rotation? I am sure you must have witnessed such things and in all such phenomena, 2 forces play a very important role to make those … Read more

## Examples of Pulleys

Pulleys have a lot of importance and tend to find applications in a lot of machinery and mechanisms. Pulley is basically a simple machine known for converting difficult tasks into simpler ones. A pulley is a simple machine made up of a rope … Read more

## Types of Pulleys

Pulleys can be of various types and are often used on the basis of what the actual need is anywhere. The range of applications where these different types of pulley systems are used is big. From drivetrains to smaller parts in mechanisms, they … Read more

## What are balanced and unbalanced forces?

Introduction When we talk about forces, we mean if there is a push or a pull. A push or pull on a body is defined as a force. The push or pull direction determines the direction of the force. Let’s use the door … Read more

## Is acceleration a vector or scalar?

In our study of physics, we deal with various physical quantities. Acceleration is one such physical quantity which is defined as the rate of change of velocity of an object with respect to time. Our current topic of discussion is whether acceleration is … Read more

## Is weight a vector or scalar?

We all know that in the study of physics most of the time we deal with two types of quantities namely scalars and vector quantities. There is a difference between scalar and vector quantities. A scalar quantity is a number that represents only … Read more
