CIE A Level Physics复习笔记3.1.4 Linear Momentum
Linear Momentum Linear momentum (p) is defined as the product of mass and velocity Momentum is the product of mass and velocity Momentum is a vector quantity - it has both a magnitude and a directi...
CIE A Level Physics复习笔记3.1.3 Newton's Laws of Motion
Newton's Three Laws of Motion Newton’s First Law: A body will remain at rest or move with constant velocity unless acted on by a resultant force Worked Example If there are no external forces actin...
CIE A Level Physics复习笔记3.1.2 Force & Acceleration
Force & Acceleration As stated on the previous page, Newton's Second Law of Motion tells us that objects will accelerate if there is a resultant force acting upon them This acceleration will be...
CIE A Level Physics复习笔记3.1.1 Mass & Weight
What is Mass? Mass is the measure of the amount of matter in an object Consequently, this is the property of an object that resists change in motion The greater the mass of a body, the smaller the ...
CIE A Level Physics复习笔记2.1.9 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, ...
CIE A Level Physics复习笔记2.1.8 Acceleration of Free Fall Experiment
Acceleration of Free Fall Experiment A common experiment to determine acceleration of a falling object which can be carried out in the lab Apparatus Metre rule, ball bearing, electromagnet, electro...
CIE A Level Physics复习笔记2.1.7 Solving Problems with Kinematic Equations
Solving Problems with Kinematic Equations Step 1: Write out the variables that are given in the question, both known and unknown, and use the context of the question to deduce any quantities that a...
CIE A Level Physics复习笔记2.1.6 Deriving Kinematic Equations
Deriving Kinematic Equations of Motion The kinematic equations of motion are a set of four equations which can describe any object moving with constant acceleration They relate the five variables: ...
CIE A Level Physics复习笔记2.1.5 Gradient of a Velocity-Time Graph
Gradient of a Velocity-Time Graph Acceleration is any change in the velocity of an object in a given time As velocity is a vector quantity, this means that if the speed of an object changes, or its...
