Download the PDF of this article. In high-throughput applications, standard triangular or trapezoidal motion profiles have been widely utilized to reach a desired position quickly. As shown in the ...

gradient = \(\frac{change~in~y}{change~in~x} = \frac{change~in~speed}{change~in~time} = \) \( \frac{change~in~metres~per~second}{change~in~seconds}\) = metres per ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Most people see this video of the SpaceX Grasshopper on a test flight and point to the funny stampeding cows. Yes, that's funny but that's not what I see. Instead, I see a great video example that can ...

This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

In many physics problems, we simply ignore the air drag force. Why? Because of two reasons. First, the effects of air drag are often small when dealing with falling balls and rolling carts (a staple ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
