Motion & Stability by Mind Map: Motion & Stability

1. Forces

1.1. Gravity

1.1.1. Attractive

1.1.1.1. Too small to observe

1.2. Electromagnetism

1.2.1. Attractive or repulsive

1.2.1.1. Electric and magnetic fields

1.2.1.1.1. Coulomb's law: Describes and predicts the effects of electrostatic forces

1.3. Nuclear interactions

1.3.1. Inside atomic nuclei

1.3.1.1. Short-range interactions

2. Interactions

2.1. Static object

2.1.1. Multiple forces that sum to zero

2.2. Interacting objects

2.2.1. Newton's 3rd law: Equal and opposite force of objects interacting

2.2.2. Newton's 2nd law: Force = mass times acceleration

2.2.3. Momentum: Mass times velocity

3. Stability

3.1. Stable system

3.1.1. small change leads to forces that return system to prior state

3.1.2. relies on feedback mechanisms to maintain stability

3.2. Unstable system

3.2.1. small change leads to forces that increase that change

3.2.2. can be static
