![]() ![]() ![]() Putting an opposite force, a force in the opposite direction which you're trying to move. Now, we might know that when you're trying to move through water, the water tends to slow you down, and it does that by For example, let's say there is a sailboat and imagine there is wind that Recap of what this means, the word net force means that if there are more than oneįorces acting on a body, we have to calculate the effective value. It says the net force acting on a body equals the mass of thatīody times its acceleration. So, where do we start? Well we can start from Newtons second law, because it has an equation for force. Or on our hands, right? Which means we need to somehowĬonnect force and momentum. We need to talk about the forces that are acting on our bodies Anyways, since in this video we want to answer questions like why it hurts more? Or it hurts less in certain situations. Mass like a ball of cotton moving with modest speed, then it has very low momentum because it's extremely easy to stop that, it almost stops effortlessly. You take something very, which has a very tiny Very massive freight train moving very fast with very high velocity, then it has super high momentum because it's extremelyĭifficult to stop that. And we can think of itĪs a number that tells us how hard it is to stop a moving body. ![]() So, what's momentum? Well, momentum, P is defined as the product of mass and velocity. Going to use momentum to answer this question. Questions might seem obvious but it isn't and there are aĬouple of ways to answer this. Soft surfaces doesn't hurt us but falling on hard surfaces do? Now the answer to these ![]() In my case a bean bag, it doesn't hurt much now. On the other hand, we know that if you are falling on something soft like a cushion or maybe Yup, that hurts a lot, pleaseĭon't try this at home, it seriously hurts. But why? Why does that happen? A similar question could be when you fall on a hard surface, it hurts. It like this, right? However, for some reason, when you move your armsĭown, it hurts less. Why do they do that? Why not just catch a ball this way? Well I'm pretty sure you Cricket, you may have noticed that whenever people catch a ball, they always move theirĪrms down like this. ![]()
