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.

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

The flow of charge in an electric circuit signifies the existence of electric current in that circuit. We can define electric current as the rate of flow of electric charges (electrons) in a conductor (for example copper or metallic wire). Flow of charge definition The flow of charge is the process of supplying or adding

In this article learn about the what is graph in physics and how to plot a basics of graphs in physics. Here you will learn about  Why we need graphs What are graphs and How to plot graphs After reading this article students would be able to define graphs and plot graphs using data on

When a PN junction is reversed biased it allows very small current to flow through it. This current is due to the movement of minority charge carriers and it is almost independent of the voltage applied.
If reverse bias is made too high, the current through PN junction increases abruptly and the voltage at which this phenomenon occurs is called breakdown voltage .

Question: When a person walks on the floor? which direction force is applied by the person to move forward?

Question: According to Newton’s third law,each team in a tug of war pulls with equal force on the another team

What then determine which team will wins it
