Acceleration Formula Acceleration is the rate of change of velocity with time.It is a measure of the change in the velocity of an object per unit time and mathematically acceleration formula is given as For describing average acceleration, we first consider the motion of an object along straight line. Suppose at time t1 object is at point P moving with velocity v1 and at time t2 it is at … Continue reading Acceleration formula Explained with Examples

Introduction about physics and studying the subject This article is mainly about use of units in physics. But before going further let us first discuss about how to avoid problems that students face while studying physics. When you study physics you must have appropriate skills or you would have to struggle a lot while studying the subject. In my experience students fail to learn physics … Continue reading Use of units in physics
Here are few problem solution for NCERT Motion class 9 solution. each solution is detailed enough to clear all the doubt I have given them some short and some long type questions Short question: Question 1: When will you say a body is in (i) uniform acceleration? (ii) non- uniform acceleration? Solution: Uniform Acceleration: A body is said to have uniform acceleration if it travels … Continue reading NCERT Motion Class 9 Solution
This article is about in-depth explanation of newton’s third law of motion. Here in this article I presume that you have a introduction of Newtons first law of motion and Newton’s second law of motion. Now Newtons first law and second law of motion deals with the effect of forces when they acts on a body. First law is about the change in the velocity of the body on the application of unbalanced forces and second law is gives the exact amount of the force needed to produce a given acceleration.
