Have you ever tried dropping two pieces of paper from the same height, and seen how they fall? You would have seen that the folded piece of paper falls to the ground faster, and more directly than the unfolded paper. This is due to air resistance. Air resistance is the force which the air exerts… Continue reading How Parachutes Work
We’ve all heard of how we see things around us when light enters our eyes. But why do some people have to wear spectacles to see either distant things or close-by things clearly? How your eyes work Light reflected off the object enters the eye through the pupil and passes through the lens. After passing… Continue reading How Spectacles Work
Have you ever wondered why it is easier to open or close a door when you apply force on the end opposite to its hinge rather than near the hinge? This is because of the concept of torque. Torque is the ability of a force to rotate an object. It is this torque which is… Continue reading How Doors Work
Most of us have seen the magical event when paper strips start ‘dancing’ and flying when a comb rubbed on clothes or hair is brought near them. This is because the comb gets charged when it is rubbed. All the objects that we see around us are made of atoms, which are small uncharged particles.… Continue reading Why does a rubbed comb attract paper strips

Why are chopping board surfaces rough and not smooth? why milk does not boil over and flow out even during the busiest morning hours? how is the water so cold in the ancient-shaped matka in… Continue reading Science In The Kitchen
We have all seen how birds in the sky fly in a v-shaped formation. But the question is why do they do so? The answer in this question lies in Physics, in the study of aerodynamics. Aerodynamics is the study of how smoothly object can move through a medium. Birds in this formation can generally… Continue reading Why do birds fly in a V-shaped formation
Have you ever wondered why a ball bounces back when you drop it on the ground? Newton’s Third Law of Motion gives us the answer: Every action has an equal and opposite reaction. When the ball is released by you, it is pulled by gravity and starts going faster and faster.When it reaches the ground,… Continue reading Why does a ball bounce off the ground?
