Newton's Second Law is concerned with unbalanced forces. Unbalanced forces produce acceleration. The greater the unbalanced force the greater the acceleration. This law is usually written as an ...

A still from the educational NASA video "STEMonstrations: Newton's 2nd Law of Motion." Here, astronaut Randy Bresnik is seen introducing the experiment he is about to conduct in microgravity ...

Acceleration and velocity Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.

If you want to model the forces on a particle moving near the speed of light (3 x 10 8 m/s), then the plain version of Newton's 2 nd Law doesn't work. However, the momentum principle still works ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

"STEMonstrations: Newton's 2nd Law of Motion" was released on Feb. 28, but the video was filmed several months ago; Bresnik has been back on Earth since Dec. 14, when he ended his 139-day space ...
