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
Physics problems with pseudo force with solutions Physics problems with pseudo force with solutions- so you well understand that these problems are going to related with non inertial frame of reference.Let’s solve these interesting numericals. A smooth inclined plane of angle of inclination 30 o is moving with a constant acceleration a as shown in
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 & 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
