## 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 […]

## Heating effect of electric current class 10 – formulas & Numerical

In this post, we will discuss the Heating effect of electric current (class 10) and list down the Heating Effect formulas or Equations of electric power and energy. And, then we will solve a bunch of numerical problems as well using these formulas. Heating effect of current formulas for power and energy The power P […]

## Key Equations from Work, Energy, Power & Simple Machines chapter

Here we enlist important key equations from the Work, Energy, Power & Simple Machines chapter. Equations related to Work, Power and the Work-Energy Theorem Let’s examine how doing work on an object changes the object’s energy. We will use cases related to a piece of rock to apply different equations from work & energy. Equation […]
