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...
IB DP Physics: SL复习笔记2.1.1 Distance & Displacement
Distance & Displacement Distance is a measure of how far an object travels It is a scalar quantity - in other words, the direction is not important The athletes run a total distance of 300 m Co...
IB DP Physics: SL复习笔记1.3.3 Solving Vector Problems
Solving Vector Problems In physics, vectors appear in many different topic areas Specifically, vectors are often combined and resolved to solve problems when considering motion, forces, and momentu...
