Explain Balanced and Unbalanced Forces
When two or more forces acting on an object produce zero resultant force, i.e. the object has no acceleration; we say that the forces are…
Explain Fundamental Forces which Exist in Nature
Though we observe different kinds of force in nature, fundamental force are of four types. Rest of them is some forms of these fundamental forces.…
Describe Nature of Force
We have a general concept about force from our daily life experiences. When we pull or push a body, then we say a force is…
Explain Laws of Falling Bodies
Galilio discovered three laws relating to falling bodies : These are called laws of falling bodies. These laws are applicable only for bodies falling from…
Mathematical Example: Equation of Motion
Example 1: A car starting from rest moves with acceleration of 2 ms-2 its velocity reach at 20 ms-1 . How long time does the…
Describe Equations of Motion
We can solve the problems regarding motion of any moving bodies by using only four equations. These equations are called equation of motion. These equation…
Mathematical Example on Velocity
Question 1: Velocity of a car increases uniformly at the rate of 5 ms-1 and after 10 s becomes 45 ms-1 . Find the acceleration…
Explain Scalar and Vector Quantity
Anything that can be measured in this physical world is called a physical quantity. When a physical quantity is measured, it has got a magnitude.…
What are the Types of Motion?
There are five types of motion: Linear Rotational Rectilinear Periodic Vibratory Linear motion: If a body is in motion along a straight line, that…
