Rotational Motion

Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be calculated by determining the distance from the axis of rotation. The net torque is equal to the product of the rotational inertia and the angular acceleration.

Cloudy climate change: How clouds affect Earth’s temperature

As the Earth’s surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds. Jasper Kirkby details an experiment at CERN that aims to do just that.

What really is gravity?

What is gravity? It keeps you on the ground and the planets orbiting the sun. But do you really know what gravity is? If you haven’t heard of General Relativity, chances are you don’t know our current theory on what gravity is.
