IB DP Physics: HL復習筆記2.3.4 Work Done
Work Done Work is defined as The amount of energy transferred when an external force causes an object to move over a certain distance If the force is parallel to the direction of the object's displ...
IB DP Physics: HL復習筆記2.3.3 Elastic Potential Energy
Elastic Potential Energy Elastic potential energy is defined as The energy stored within a material (e.g. in a spring) when it is stretched or compressed It can be found from the?area under the for...
IB DP Physics: HL復習筆記2.3.2 Gravitational Potential Energy
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...
IB DP Physics: HL復習筆記2.3.1 Kinetic Energy
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...

IB DP Physics: HL復習筆記2.2.4 Newton’s Third Law
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 ...
IB DP Physics: HL復習筆記2.2.3 Newton’s Second Law
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 ...
IB DP Physics: HL復習筆記2.2.2 Newton’s First Law
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 ...
IB DP Physics: HL復習筆記2.2.1 Free-Body Diagrams
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...
IB DP Physics: HL復習筆記2.1.8 Terminal Speed
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...
