Newton’s Law of Motion

newton's second law and force

Newton’s second law and equation of Force

Newton’s second law Newton’s second law states that the rate of change of momentum of a body is equal to the net force applied on it. So it’s evident that the second law of Newton was stated in terms of momentum.Mathematically it can be stated this way: Fnet = (mV-mU)/t. Here, U is the initial

numerical problems in physics for class 9

Physics problems for class 9 – numericals with solutions

Physics problems for class 9 (CBSE)–numericals set1 This set of Physics problems for class 9 students of CBSE/ICSE/HS boards cover Newton’s Laws of motion, Force, linear motion equations and Gravitation. Hope the students will like this set and try to solve the numerical problems themselves. I am providing the solutions as well, but you should

Newton’s laws and Contact Forces between blocks – your must read

Newton’s laws & contact Forces between blocks in Mechanics Newton’s laws of motion gives us concepts of force (first law), measurement of force with its equation (second law), and reaction of force (3rd law). Today we will discuss an interesting topic of mechanics. It will cover a few interesting applications of Newton’s Laws and analyse

pseudo force

Pseudo force in Physics-did you know this?

Pseudo force – Is it a real force?  Some forces are real, whereas others are not. Real forces have some physical origin, such as a gravitational pull, frictional force or tension of string. In contrast, fictitious force or pseudo force arises simply because the observer is in an accelerating or non-inertial frame of reference, such
