IB DP Physics: SL复习笔记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: SL复习笔记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: SL复习笔记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...
IB DP Physics: SL复习笔记2.1.7 Projectile Motion
Projectile Motion The trajectory of an object undergoing projectile motion consists of a?vertical?component and a?horizontal?component These need to be evaluated separately Some key terms to know, ...
IB DP Physics: SL复习笔记2.1.6 Acceleration of Free Fall Experiment
Acceleration of Free Fall Experiment The acceleration of free fall, g, is defined as: The acceleration of any object in response to the gravitational attraction between the Earth and the object Any...
IB DP Physics: SL复习笔记2.1.5 Uniform Acceleration
Equations of Motion for Uniform Acceleration Deriving Kinematic Equations of Motion The kinematic equations of motion are a set of four equations that can describe any object moving with?constant?a...
IB DP Physics: SL复习笔记2.1.4 Graphs Describing Motion
Motion Graphs Three types of graphs that can represent motion are?displacement-time?graphs,?velocity-time?graphs, and?acceleration-time?graphs Displacement-Time Graph On a?displacement-time graph… ...
IB DP Physics: SL复习笔记2.1.3 Acceleration
Acceleration Acceleration?is defined as the?rate of change of velocity In other words, it describes how much an object's velocity?changes?every?second The equation below is used to calculate the av...
IB DP Physics: SL复习笔记2.1.2 Speed & Velocity
Speed & Velocity Speed The?speed?of an object is the distance it travels every second Speed is a?scalar?quantity This is because it only contains a magnitude (without a direction) The?average s...
