Let's explore what relative density is.

Let's solve a numerical on 2 free falling bodies. One stone dropped and another one, thrown up, when and where do they meet?

Let's solve problems involving objects in free fall, and we are given/asked the total time to up and then come back down.

Let us calculate pressure due to the weight of a Gorilla and monkey.

Why submarines get crushed under water? Due to immense pressure in liquids. Let's learn about pressure in liquids.

Let's solve problems on one body in free fall.

What are thrust and pressure? Well, that's exactly what we will explore in this video. We will also learn the formula and units of pressure, by taking various examples.

Let's explore how the force between masses change when the distances and the masses change using the universal law of gravity.

Let's explore what Archimedes principle & buoyant force is.

Let's solve 2 problems in finding the mass of displaced water. 

Let's learn why floatation depends on density.
