mechanics for high school students: a few posts

Here are a few post links on fundamental mechanics which we have posted in last few weeks. Friction Definition                   Newton’s Second law Newton’s laws and a few application case studies pseudo force Numerical problems for class 9 / Physics problems class 9 Physics problems on Pseudo Force

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


Equilibrium of a rigid body-conditions and physics

Equilibrium of a Rigid body A rigid body is said to be in mechanical equilibrium, if both its linear momentum and angular momentum are not changing with time. In other words, the body is in mechanical equilibrium when it has neither linear acceleration nor angular acceleration.This means the conditions for equilibrium can be expressed as
