I learned about this topic from a Lifehacker article titled: [The Reason Why Cats Always Land on Their Feet, Even When Falling from High Places].<\/p>\n<p>Watching the video, you can see how skillfully a cat uses its body to &#8220;absorb the impact&#8221; of the landing. But what exactly does it mean to &#8220;absorb impact&#8221;?<\/p>\n<p>Today, let&#8217;s unpack this feline super-technique together, using the concepts of &#8220;Momentum&#8221; and &#8220;Impulse&#8221; from high school physics!<\/p>\n<h3>Unlocking the Cat&#8217;s &#8216;Super Landing&#8217; with High School Physics<\/h3>\n<p>In physics, the &#8220;oomph&#8221; or &#8220;force of motion&#8221; of a moving object is called &#8220;Momentum&#8221;. It is determined by the simple formula: Mass (Weight) \u00d7 Velocity (Speed). A cat falling from a great height has a significant amount of &#8220;Momentum&#8221; right before it hits the ground.<\/p>\n<p>The act of landing means this &#8220;Momentum&#8221; must be reduced to &#8220;Zero&#8221;\u2014instantly.<\/p>\n<p>To stop an object (or change its momentum), you need something called &#8220;Impulse&#8221;. Impulse is calculated as Force \u00d7 Time.<\/p>\n<p>If we denote the force the cat receives from the ground as F, and the time the cat&#8217;s paws are in contact with the ground as t, the following relationship holds true:<\/p>\n<p style=\"text-align: center;\">mv\u3000\u2212\u3000Ft = 0<\/p>\n<p style=\"text-align: left;\">(Initial Momentum) \u2212 (Impulse) = (Final Momentum, which is 0 because it stops)<\/p>\n<p>Rearranging this gives us the key equation:<\/p>\n<p style=\"text-align: center;\"><b>Ft = mv<\/b><\/p>\n<p style=\"text-align: center;\">(Impulse = Initial Momentum)<\/p>\n<p>Here is the most critical point. The amount of &#8220;Momentum (mv)&#8221; the cat must change for a safe landing is fixed\u2014it&#8217;s determined by the height of the fall. The cat can&#8217;t change this value. So, what would happen if the cat landed with a sudden &#8220;thud!&#8221; (meaning the time t is very small)? Since Ft equals a constant amount of momentum, a small t means the force F on the paws would have to be incredibly large. This enormous force is the true nature of &#8220;impact,&#8221; which could lead to severe injuries like broken bones.<\/p>\n<h3>The Cat&#8217;s Superb Technique: Buying Time<\/h3>\n<p>So, what does the cat do? Let&#8217;s look at the slow-motion footage again. The cat approaches the ground with its legs initially extended straight.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-24823 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/04\/9c8f28bb07a1e2554651ba7cdcf7041c.jpg\" alt=\"\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8 2016-04-25 5.30.33\" width=\"638\" height=\"359\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/04\/9c8f28bb07a1e2554651ba7cdcf7041c.jpg 638w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/04\/9c8f28bb07a1e2554651ba7cdcf7041c-300x169.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/04\/9c8f28bb07a1e2554651ba7cdcf7041c-320x180.jpg 320w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><\/p>\n<p>The key is that its legs are not bent from the start.

Recall the equation Ft = (constant momentum). By using its flexible body to make the landing time t longer, the cat successfully reduces the force F its paws receive from the ground (technically called the Normal Force). This, fundamentally, is what &#8220;absorbing the impact&#8221; really means.<\/p>\n<h3>Impulse Control in Everyday Life<\/h3>\n<p>In fact, this very same technique is used in things we do every day.<\/p>\n<p>Take, for example, Kendama (the cup-and-ball game). When you catch the ball in the cup, you slightly bend your knees to &#8220;give&#8221; at the moment of impact, right? That subtle downward motion is also a way to extend the time t until the ball stops, reducing the force F the cup exerts on the ball and preventing it from bouncing away. If you kept your knees locked and tried to catch it with a sudden stop, the ball would just spring back out.<\/p>\n<p>The cat, using its innate flexibility and instinct, masters this &#8220;Impulse Control&#8221; perfectly. It&#8217;s astonishing to realize that a simple cat jump, which we often overlook, is filled with such sophisticated physics!<\/p>\n<h3>Inquiries and Requests<\/h3>\n<p>Bringing the wonders and fun of science closer to you!
