Newton's Second Law (Chapter 2 Lesson 3)

Newton's Second Law (Chapter 2 Lesson 3)

Author: Jason Fritz

I know what  Newton’s second law of motion is?

I know that Force = Mass x Acceleration (F=MA)

I know how centripetal force can affect circular motion?

•Unbalanced forces cause an object to speed up, slow down, or change direction.
•Newton’s second law of motion relates an objects acceleration to its mass and the net force on the object.
•Any motion in which an object is moving along a curved path is circular motion.

Newton's Laws: Crash Course Physics #5

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.

Uniform Circular Motion: Crash Course Physics #7

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.

Newton's Second Law of 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.

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt breaks down Isaac Newton's Second Law of Motion and how it can effects the flight of the football as place kickers shoot for the goal posts. Professors Tony Schmitz of the University of Florida and Jim Gates of the University of Maryland explain why it truly can be "hit or miss" when it comes to striking a football.
