## Examples and Practical use of Inelastic collisions

In this post, we will study a few examples of Inelastic collisions. Also, we will study an important practical use of Inelastic collisions.

## Equations valid for elastic collisions

In this post, we will briefly mention the equations valid for elastic collisions. We can use these equations to solve numerical problems related to elastic collisions. The Equation for the conservation of momentum (for elastic collision) Now, to solve problems involving one-dimensional elastic collisions between two objects, we can use the equation for the conservation […]

## Explosion and Conservation of Momentum

An explosion can be thought of as a single object separating into two or more fragments. In this post, we will see if the law of conservation of momentum is maintained during an explosion. We will solve related numerical problems as well. Some familiar examples of explosions are: a bomb blowing into fragments a bullet […]

## Car safety, momentum & force – GCSE Physics

Car safety, momentum & force – GCSE Physics – The force on a person in a car crash can be very large and the force can be worked out from the deceleration in a crash. You can also work out the force in a crash using the equation for momentum. Car safety is designed using the concept of momentum and force related to a car crash. The objective is to keep the force on a person as small as possible. Let’s take an example of a car travelling a steep road.

## Numericals on Conservation of Momentum class 11

Numerical problems on collisions of objects in two dimensions. We will solve the collision problems using axial-vector components and the law of conservation of momentum.

## Newton’s Cradle & Momentum Conservation

Using Newton’s Cradle apparatus very familiar example of momentum conservation is demonstrated. The law of Conservation of Momentum states that the change in the total momentum of a system is zero when the net force on the system is zero. With the help of Newton’s Cradle, we can demonstrate the conservation of momentum with a […]

## Numerical on Momentum class 9

This post is to solve some Numerical on Momentum for class 9. These are numerical problems related to momentum and impulse concepts in physics. Impulse-momentum theorem and Impulse equation help a lot to solve this momentum numerical set. This set is good for students of class 9 & class 10 (covering grade 9 and grade […]

## Relation between kinetic energy and momentum | Derivation of p=√(2mk) or momentum-KE equation

In this post, we will find the relation between kinetic energy and momentum. We will also derive the momentum-kinetic energy equation or p=√(2mk) equation. This momentum-KE equation presents the relation between momentum(p) and kinetic energy(K). momentum-kinetic energy equation | p=√(2mk) The relation between momentum(p) and kinetic energy(K) of an object of mass m can be […]

## Numericals on Impulse

Let’s solve a few selected Numericals on Impulse. These are basically numerical problems based on Impulse and its relationship with Momentum. A few are graph-based problems. If you want to have a quick revision on Impulse and Momentum and get their formulas, then you can do so by going through our posts. The links are […]

## What is the Law Of Conservation Of Momentum? | derivation

If there is no net external force on a system, the total momentum of the system remains constant. This is the law of conservation of momentum. (also known as the principle of conservation of momentum). Here, by the term momentum, we mean Linear Momentum. When the net external force acting on a system is zero […]

## Rocket Equation Derivation along with Rocket Acceleration formula

Rocket Equation Derivation is the objective of this post. We will also derive the Rocket Acceleration formula here as we go forward. When the fuel of rocket burns the fuel gas gets expelled backward at a high velocity. This results in a force being applied on the rocket in the forward direction and the rocket […]

## How do Rockets work?

How do rockets work? As the rocket engines operate, some kind of fuel (liquid or solid) is burnt. The engines continuously eject burned fuel gases. As these exhaust gases have both mass and velocity, they have some momentum as well. By the principle of conservation of momentum, the rocket’s momentum changes by this same amount […]

## State and Prove Impulse Momentum Theorem with derivation of equation

In this post, we will State and Prove the Impulse Momentum Theorem with the derivation of the equation. As evident, this theorem or principle is related to impulse and momentum. Hence a prior knowledge of these two will help.Related study links are provided here: Read about Momentum and here you can read about Impulse as […]

## Impulse – definition, formula, unit

Impulse Definition If a force acts on a body for a very brief time then we say that an impulse is generated. As example, when we hit a ball with a bat for a brief period of time then an impulse is generated. Here a considerable amount of force acts on a body for a […]

## Momentum – Definition, Meaning, and Formula

In this post, we will cover the definition and formula of Momentum (Linear Momentum). We will also discuss what it actually means in physics. Momentum Definition | Linear Momentum By Momentum, we mean inertia in motion. More specifically, Linear Momentum or Momentum is defined as the product of the mass and velocity of an object. […]
