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 ...

**Pre-reqs:** None. I intend to talk about forces and force diagrams, but there is a more fundamental question to address first. What is a force? Most texts define it as a push or a pull. That really ...

Find out more about Sir Isaac Newton’s laws of force and motion at the amusement park, Silverwood. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything.

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 this ...

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 ...

This series of short explainer films with Professor Brian Cox comprises six clips focused on forces, speed and motion. Each clip uses simple terms and concrete examples to explain deep concepts that ...

Electromechanical actuators are mechanical actuators where the control knob or handle has been replaced by an electric motor. The rotary motion of the motor is converted into linear displacement. The ...

One of the most misunderstood principles regarding linear bearings is something called the 2:1 Ratio. Understanding it will help engineers avoid the problem of stick-slip. Back in the 1980s, Pacific ...
