Surface Charge Density Formulas & Examples
Surface Charge Density is the amount of charge per unit of a two-dimensional surface area. It is a measure of how much quantity of electric charge is accumulated over a surface. It is expressed by the symbol σ and the unit in the SI system is Coulombs per square meter i.e Cm–2. If q is…

Solved Examples on Displacement Formula
Question 1: Find the displacement covered by an object which accelerates from rest to 60 m/s in 3s. Solution: Initial velocity = 0 and final velocity = 60 m/s. Time taken = 3s. Therefore, acceleration = 60/3 = 20m/s2. Displacement (S) = ut + ½ at2 = 90 m Question 2: Find the displacement of…

How to Calculate Displacement
We find the displacement by determining the object’s initial and final position. The displacement formula is given by: Δx = xf − xi….. (1) where, xf is the final position, xi is the initial position, and Δx is the change in the position of the object. Let’s say, I kept a golf ball on the…

An Introduction to Displacement
Displacement is the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity. It is shown with an arrow that points from the starting position to the final position. For example, an object moved from position A to position B, then the position of…

Things to Remember
At the atomic level, when atoms or molecules are pulled apart from each other and gain potential energy with a restoring force still existing, the restoring force might create tension. Each end of a string or rod under such tension could pull on the object it is attached to, in order to restore the string/rod…

What is Tension Force?
In Latin, the word “tension” means “stretching”. The force which is applied to the length of a flexible area such as a rope or a cable, or chain is referred to as tension formula force in physics. We know that a push or pull is indicated by a tension force. In physics, we are dealt…

How to Calculate Tension Force
Tension refers to the pulling force transmitted axially by the means of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of the said elements.

Angular Acceleration Formula
The rate at which the angular velocity changes with time is known as the angular acceleration in circular motion. It is also known as rotational acceleration. The quantity has both magnitude and direction, so it is a vector quantity. Angular acceleration is denoted by α. Let θ be the angular displacement, ω� be the angular…
