Newton’s 3rd Law of Motion

Newtons 3rd law of motion 3

Newton’s Third Law is very popular law and you must have probably heard some version of it before studying it in your course. Let us see what the law states. Statement: All forces come in pairs. If Object 1 exerts a force on object 2 then object 2 must exert ...

Newton’s 2nd Law Of Motion

newton 2nd law 8

In this article we are going to state and understand Newton’s second law of motion. But before we do, we will go through some important concepts which will help us understand Newton’s second law efficiently. Free Body Diagram Let us first understand what is a Free-Body-Diagram (FBD). Free-Body-Diagrams are diagrams ...

Newton’s 1st Law of Motion

Newton 1st law 2

Sir Isaac Newton was one of the greatest physicist and responsible for development of laws of motion, laws of gravitational attraction and calculus among other things. In this article we will discuss Newton’s First Law of Motion Statement of the First law of Motion: An object at rest will remain ...

Relative Motion

relative motion 3

In Physics, motion is always described from the point of view of an observer. If two observers are moving different manners, they might observe the same event in differently. Lets see a very simple example. Say you are on a train, which is moving with a constant velocity – ‘v’ ...

Vectors and Scalars

Vectors & Scalars 4

In Physics we will encounter two very common types of quantities: Vectors and scalars. Scalars Definition of Scalar Scalars are quantities which only have magnitude. Scalars can be added and subtracted like normal numbers. Examples: Quantities like mass, temperature, volume; charge, time, etc are all scalar quantities. Their magnitudes are ...

Projectiles

Projectile 4

What is a projectile? A projectile is any object which is only acted upon by the force of gravity. A ball thrown in the air for example is an example of projectile. We can see examples of projectile motion in our day to day life. Objects falling down, objects thrown ...

Kinematic Equations

Kinematic Eq 1

Kinematic equations are used to describe and analyze motion of particles with constant acceleration. (constant acceleration is an essential assumption. If the body has variable acceleration then we will have to figure out different equations)   Kinematic equations can give us information about five key variables involved with an object ...

Defining and Graphing Motion

Kinematic Eq 2

In this article we will discuss the different aspects of motion such as distance, displacement, velocity, etc. and how to comprehend these characteristics through graphs. Position Position is simply the location of the particle or body. In Cartesian coordinate system, the position is given by the (x, y, z) co-ordinates. ...
