## How to solve leaning ladder equilibrium numerical?

In this post, we will solve a numerical problem based on the equilibrium of a leaning ladder. To do this you need to first understand the conditions of equilibrium. If you require some revision then you can quickly go through our physics tutorial on the equilibrium conditions first, before attempting this numerical. Anyways, let’s begin […]

## Mechanical advantage Formula – MA formula

In this post, we will talk about the Mechanical advantage formula (MA formula) for different simple machines. Mechanical advantage Formula | MA formula The Mechanical advantage formula (MA formula) can be written as follows: (1) Mechanical Advantage MA = output force/input force (2) Mechanical Advantage MA = resistance force/effort force. The machine uses this resistance […]

## NCERT Solution of Laws of Motion problems – class 11 physics

NCERT solutions for class 11 physics chapter 5 laws of motion – This chapter covers selected problems from the chapter laws of motion. Here we are solving selected problems both from the Exemplar and NCERT Physics textbook. If any problem needs some coverage of fundamentals we are catering that also. We are giving the reference […]

## 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 […]

## Contact Forces between blocks – Application of Newton’s laws

Application of newton’s laws: Newton’s laws of motion give us concepts of force (first law), measurement of force with its equation (second law), and the reaction of force (3rd law). Today we will discuss an interesting topic of mechanics – the application of Newton’s laws. It will cover a few interesting applications of Newton’s Laws […]

## Pseudo force in Physics-did you know this?

What is a pseudo 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 the string. In contrast, fictitious force or pseudo force arises simply because the observer is in an accelerating or non-inertial frame of reference, such as […]

## Equilibrium of a rigid body-conditions and physics

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. For a body of finite size to be in equilibrium:(i) the resultant force on […]

## Angular Momentum

When an object moves with an angular speed ω along the circumference of a circular path of radius r, then we say that it has angular momentum. Angular momentum is the rotational equivalent of linear momentum and is defined as the moment of Linear momentum. It depends on 2 quantities, one is rotational inertia or […]
