Circular motion
Circular motion is where an object goes around in a circle. You can imagine the object movement along the circumference of a circle or rotation along a circular path. Circular motion can be uniform...
Time period of conical pendulum
This article explores the time period of a conical pendulum. The time period of a conical pendulum is the time it takes for one revolution. Remember; [IMAGE]
Conical Pendulum
A conical pendulum is similar to the simple pendulum except the motion also involves a circular motion about the point of suspension thus creating a conical shape. The conical pendulum was first studied by...
Refraction of light
Generally, snell’s law for light travelling from medium 1 to medium 2 can be written as; [IMAGE]
Deriving (SUVAT) equations of motion
This article explores how to derive the (SUVAT) equations of motion. The SUVAT equations (equations of linear motion) only work when the acceleration is constant. They will not work for varying acceleration. They are...
Linear & Circular motion formulae
This article explores the basic formulae of linear & circular motion formulae. Linear motion (SUVAT) equations Let us look at linear motion first. Below is a list of linear motion equations that we shall...
