I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion.

Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of Rotational Motion!

You will learn about "Newton's 2nd law of motion" in this video. Newton's 2nd law states that the rate of change of momentum of an object is directly proportional to the unbalanced force in the direction of force. It states that force is equal to mass times acceleration.
If Newton applies force on a rock, the force applied by him causes the rock to move only slightly. Now, if the horse applies force on the same rock, the rock moves faster, i.e. more acceleration is produced. This is because the force applied by the horse is more than Newton. Hence, force is proportional to acceleration.
Oh! Mr. Smart is trying to keep Newton and the horse apart. He is applying equal force on both. However, as compared to the horse, the mass of Newton is comparatively lesser. So, Mr. Smart finds it easier to keep Newton away as compared to the horse. Thus, Force is proportional to mass. Hence, we can conclude from the two cases that force is directly proportional to the product of mass and acceleration.
