Gravitational Potential Energy Gravitational potential energy (Ep) is energy stored in a mass due to its position in a gravitational field If a mass is lifted up, it will gain Ep (converted from ot...
Kinetic Energy Kinetic energy (Ek) is the energy an object has due to its motion (or velocity) The faster an object is moving, the greater its kinetic energy When an object is falling, it is gainin...
Friction Friction is a force that works in opposition to the motion of an object It occurs between two solid bodies that are in contact with one another The opposition of friction slows down the mo...
Applying Newton’s Laws of Motion Newton's laws of motion are strong tools to understand the motion of objects with forces acting upon them Below are two worked examples demonstrating different situ...
Newton’s Third Law Newton’s third law of motion states: Whenever two bodies interact, the forces they exert on each other are equal and opposite Newton’s third law explains the following important ...
Newton's Second Law Newton's Second Law states: The resultant force is equal to the rate of change in momentum. The change in momentum is in the same direction as the resultant force This can also ...
Newton’s First Law Newton's First Law states: A body will remain at rest or move with constant velocity unless acted on by a resultant force If the net force acting on an object is zero it is said ...
Vectors In physics, during force interactions, it is common to represent situations as simply as possible without losing information When considering force interactions objects can be represented a...
Fluid Resistance & Terminal Speed Fluid Resistance When an object moves through a fluid (a gas or a liquid) then there are resistive forces for that movement. These forces are known as drag for...
