英国大学需要IGCSE成绩吗？
一些学生和家长都误以为GCSE没有A-Level这么重要，其实这是一个误区！两者的区别就像国内的“高考”和“中考”，重要程度相当。英国大学需要IGCSE成绩吗？以QS世界大学排名英国Top10大学为例，我们来看看你的IG成绩是...
IB DP Physics: SL复习笔记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: SL复习笔记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: SL复习笔记2.2.6 Friction
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...
IB DP Physics: SL复习笔记2.2.5 Applying Newton’s Laws of Motion
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...
IB DP Physics: SL复习笔记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: SL复习笔记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: 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...
