Determination of acceleration of gravity (g).
Periodic motion (Simple Harmonic Motion).
Understand the motion of a simple pendulum under small angle approximation.
Gravity exerts a force on every object. This force is proportional to the mass of the object. The proportionality constant is the acceleration of gravity "g". A simple pendulum is made of a long string and a tiny metal sphere, steel or preferably lead (higher density). The period of oscillation of a simple pendulum may be found by the formula:
Measuring the period of oscillations of a simple pendulum under the action of gravitational force at a small angular displacement ө for different lengths for the thread.
I love the idea of virtual labs. It's gonna be something that takes our R&D and work in labs to another level. And I look forward to seeing what PraxiLabs can do with it.

Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab solution: PraxiLabs.

PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs.

With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.
