Newton's 2nd Law of Motion

In this video, Newton's 2nd Law of Motion is demonstrated in several different ways; first the video shows the effects of mass on acceleration in space as compared to on Earth. Several different examples follow this as the video moves on to explain the effects of force on acceleration, specifically the force of friction.
I think it is super cool how Newton's 2nd Law is shown in space and it is helpful as we can take gravity out of the equation and just focus on the relationship between force, acceleration, and mass. According to Newton's 2nd Law, acceleration is directly proportional to force and inversely proportional to mass. This means that acceleration will increase as force increase, while it will decrease when the mass of the object increases.
The relationship between mass and acceleration is very clearly demonstrated in the first part of the video. I think the later parts of this video are less clear in their explanation of force in relation to acceleration. However, this is still a helpful and unique resource. I hope this broadens your understanding of Newton's 2nd Law! Enjoy!
