Motion

1. Vector

1.1. Velocity

1.1.1. Distance traveled/Time taken(With direction)

1.1.2. Terminal Velocity(Drag force=Weight)

1.1.3. Constant Velocity(Direction,speed not changed)

1.1.4. Velocity v Time graph(Gradient=Acceleration,Area=Displacement

1.2. Acceleration

1.2.1. Speed change/Time change

1.2.2. Constant acceleration(In one period,the accelerating not changed)

1.3. Displacement

1.3.1. Distance travelled(With direction)

1.4. Resultant&Conponent Force

1.4.1. Cosine Rules  F=√(F1²+F2²-2*F1*F2*cosβ)

1.4.2. Draw a picture

1.4.3. Use Trigonometric functions（Whenβ=90）

2. Size

3. Size+Direction

4. Scalar
