Science aid: Forces and motion

Welcome to Forces and Motion

This unit is about force and motion. A common topic in Physics that is very important for fields such as engineering. This unit includes articles that look at:

Newton's three laws of motion

Speed-time graphs

terminal velocity in a skydiver

Forces in Practice	Terminal velocity with example of skydiver and extension of a spring and rubber band.
Motion and Speed	Differentiating speed and velocity, acceleration, speed/time graphs, and stopping distance.
Power and Work	Equations of power and work, kinetic and potential energy. Isaac Newton's three laws of motion explained.
Pressure	We have a look at pressure; the pressure equation with worked example and gas and air pressure.
