Physics

In this article I would discuss what are free body diagrams and how to make one. Free body digrams are of immense importance when one want to study physics. You will find great deal of their usage while studying mechanics and tou can hey have equal inportance when it comes to other branches of physics. However i will discuss their usage and construction in context to mechanics.

Pounds and kilograms are two of the many units used for the measurement of mass. Physical quantities need units for their measurement. We need standard well-defined units for measurement of physical quantities. Although both pound and kilogram are units of mass but there are some profound differences between these two units of mass. A pound

Electrical circuits are one of the most important things that govern the working of any device that runs on electricity. Circuits are the pathways that guide the powerful electric current to your homes and the electronic devices making them truly functional. The electrical circuits are hugely based upon two types of combinations which are ‘Parallel’

Mass Vs. Weight Comparing and Understanding differences Mass and weight, most of the time both physical quantities are used interchangeably in our day-to-day life. People mix them up most of the time, but both these quantities are not the same. The basic difference between weight and mass is that mass is the amount of matter

On this page we are providing some frequently asked questions on the concept of force along with their answers. Please note that these questions on the concept of force are not numerical questions. These are some basic conceptual questions and students must be familiar with these concepts to solve numerical problems in this topic. Notes

This tour is given to give the feel of the whole chapters plus the type of questions and ways to tackle them.This is quite beneficial for anybody studying One dimensional Motion.

Description:
One dimensional Motion is the study of the motion along an straight line.Complete Study material has been provided at the below link

Motion in a Two dimensional Plane

Select a coordinate system and resolve the initial velocity vector into x and y
components.
Find out acceleration in each direction and solve in each direction according to one rectilinear motion equation.
if the acceleration is in vertical direction only.Follow the techniques for solving constant-velocity problems to analyze the horizontal motion. Follow the techniques for solving constant-acceleration problems to analyze the vertical motion. The x and y motions share the same time of flight t.

Question 1A ball of mass 100 g is projected vertically upwards from the ground with a velocity of 49 m/s. At the same time, other identical ball is dropped from a height of 98 m to fall freely along the same path as followed by the first ball. After some time two balls collide and
