Understanding Specific Latent Heat Specific Latent HeatThe amount of heat required to change the phase of a substance depends on the mass and the type of material of the substance.A small ice cube melts quickly but a large block of ice melts very slowly…

What Do You Mean By Thrust And PressureThrustThe force acting normally on surface is called ‘thrust’.This is a vector quantity.It is measured in newton (N).PressureThe thrust on an unit area of a surface is called ‘pressure’. \(\text{Pressure}=\frac{\tex…

Errors in MeasurementsSince no measurement can be absolutely accurate, there will always be some sort of error in a measurement. An error is the difference between the measured value and the actual value.If an error cannot be eliminated or reduced, it mu…

What is Atmospheric PressureScientists discovered atmospheric pressure in the seventeenth century. This discovery uncovered an interesting fact that air actually has weight! The weight of the atmosphere presses down on the Earth’s surface and creates a p…

How do you Measure the Refractive Index?The law of refraction states that:The incident ray, the refracted ray and the normal all lie in the same plane.The ratio of the sine of the angle of incidence, i to the sine of the angle of refraction, r is a cons…

Understanding Pressure Using Pascal’s Principle A boy applies pressure on a tube of toothpaste. The pressure applied to the tube is transmitted throughout the toothpaste and forces it out of the opening of the tube. Figure shows a boy holding a plastic b…

What is Refraction of Light When a spoon is immersed into a glass of water, the spoon appears bent or broken as shown in Figure (a). When a part of the word PHYSICS is covered with a glass slab as shown in Figure (b), the covered letters appear displace…

What Is Distance And Displacement In Physics The path length between the initial and final positions of the particle gives the distance covered by the particle. Distance is defined as the total length of the path travelled from one location to another.Th…

Understanding Bernoulli’s Principle Football fans have always marvelled at how a professional footballer can execute a banana kick, sending the ball in a curved path to score a goal. Understanding the Bernoulli’s principle will help football fans to und…

How Do You Find Buoyant ForceBuoyancy When a body is immersed in a liquid, the liquid exerts an upward force on the body called as the ‘upthrust‘ or ‘buoyant force.’Factors affecting upthrust: 1. Larger the volume of the body submerged in the liquid, gr…
