Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On ...

Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

I see this problem all the time. The idea that if you apply a constant force on an object, it should move at a constant speed. Really, this is what Aristotle would say, right? There are two course ...

Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." ...

So with these problems, Newton and others had to build this force-motion model through other means. They took a theoretical approach using the data from the motion of the planets orbiting the Sun.

New study connects running motion to ground force, provides patterns for any runner Date: January 31, 2017 Source: Southern Methodist University Summary: Researchers have developed a concise ...

In this lesson from the Chemical Educational Foundation, apply the concepts of pressure and Newton's laws of motion to build balloon rockets.

Find out how forces and motion make our world move in the Science Trek: The Web Show.
