Vectors in Physics|Types In physics, Vector quantities are that quantities which have a magnitude and a direction. If we take force as an example, we can show it in terms of the magnitude of the force and the direction of the force. Such quantities in physics are called vector quantities. When we take temperature as an example, ….  Read More

      Speed, Velocity And Acceleration: Concepts & Differences To the layman, speed, velocity and acceleration may just sound like different ways to describe how fast you are going, but they actually mean very different things. The distinction between each term is essential to the study of kinematics – the study of how objects ….  Read More

Equations of Uniformly Accelerated Motion   Suppose you are driving a vehicle on a road. The velocity of the vehicle is never uniform. Its velocity increases and decreases randomly. As you move the velocity of the vehicle on the road keeps on changing and this is said to be accelerated motion. Let us study the different ….  Read More

  Motion – Equation of uniformly Accelerated Motion, With Focus on Position Path Length and Displacement .   Motion in a Straight Line We see leaves falling from trees and water flowing from the river. We walk, we run, we drive a car these are the activities that we carry out in our day to ….  Read More

  Lesson 7 Home Work and Answers Question Derive the following equation for a uniformly accelerated motion where the symbols have their usual meanings: v2=u2+2as Solution From the first equation of motion, v=u+at t=v−ua………..(i)   For a uniformly accelerated motion, Average velocity=v+u2………..(ii)   Displacement=Average Velocity×Time     Substituting from (i) and (ii), s=(v+u2)×(v−ua) ∴v2=u2+2as

    Equilibrium of Forces.   If the body is under the action of several forces and is at rest or moving with a uniform velocity it is said to be in equilibrium. Equilibrium of forces has different types   Types of Equilibrium of Forces Static equilibrium Dynamic equilibrium Static Equilibrium If the body is at rest (zero velocity ….  Read More

Principle of Moments The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point. Equation Moment =force F x perpendicular distance from the pivot d. Moment = Fd Apparatus A uniform metre rule, retort stand, boss and clamp, two 100 ….  Read More

  Archimedes Principles Archimedes’ Principle and Buoyancy LEARNING OBJECTIVES By the end of this section, you will be able to: Define buoyant force State Archimedes’ principle Describe the relationship between density and Archimedes’ principle When placed in a fluid, some objects float due to a buoyant force. Where does this buoyant force come from? Why ….  Read More

      Lesson 11 Assignment on Archimedes Theory   Class Exercise 1 and solution   An upright 5cm long cylinder is submerged in water. The top of the cylinder is 2cm below the surface. The upwards buoyant force acting on the cylinder is 5N. We move the cylinder 10cm deeper. What is the upwards buoyant force now?       Answer ….  Read More

    Projectile Motion Motion in a plane is also referred to as a motion in two dimensions. For example – Circular Motion, Projectile Motion, etc. For the analysis of such type of motion (i.e. Projectile Motion), the reference point will be made of an origin and the two coordinate axes X and Y. One of ….  Read More
