Chapter 3 + 4 von Mind Map: Chapter 3 + 4

1. Chapter 3-Acceleration and Newton's 2nd Law

1.1. Newton's 2nd law-Acceleration

1.1.1. Acceleration=rate of change of velocity

1.1.2. Velocity=rate of change of position

1.1.3. SI units

1.1.3.1. Force=N

1.1.3.2. Acceleration=m/s2

1.1.4. Average Acceleration

1.1.4.1. Change in velocity/Change in time

1.1.5. Instantaneous Acceleration

1.1.5.1. Limit of Change in velocity/Change in time

1.2. Velocity

1.2.1. Average Velocity

1.2.1.1. Change in positon/change in time

1.2.2. Instantaneous Velocity

1.2.2.1. Limit of change in positon/change in time

1.2.3. Position vs. Velocity

1.2.3.1. rise/run

1.3. Position and Displacement

1.3.1. Position=Direction+Distance

1.3.1.1. Origin=reference point

1.3.2. Displacement=Change of position vector

1.3.2.1. final position vector-initial postion vector

2. Chapter 4-Motion with a changing velocity

2.1. 2 Essential relationships

2.1.1. Change in velocity over a period of time= acceleration x elapsed time

2.1.2. Average Velocity=1/2(final+initial velocity)x change in time

2.2. Other Relationships

2.2.1. -Velocity with a +Acceleration=Decreasing Speed

2.2.2. +Acceleration=Increasing velocity

2.2.3. Increase in speed=positive velocity and acceleration

2.3. Motion Diagram

2.3.1. Shows the positon of an object at certain time intervals

2.4. Free Fall

2.4.1. Apparent weight=0

2.4.2. Acceleration=9.8m/s^2

2.5. Measurements:

2.5.1. Sum of forces: N+mg=ma

2.5.2. Angle of elevation

2.5.2.1. angle of initial velocity above horizontal
