Motion & Stability

1. Force & Motion

1.1. Force can cause a change in motion of one or both of interacting objects

1.1.1. Static Object: multiple forces acting on it but sum to zero

1.1.2. If total force is not zero, motion will occur

1.1.3. Force on object can change shape or direction of object

1.1.4. Force exerted by 1st object to 2nd has same amount of force from 2nd to 1st in opposite direction

1.2. Force= mass x acceleration

1.3.1.1. Objects pull or push each other when they collide

1.3.1.2. Friction can cause a change in object's motion and speed

1.3.2.1. Force acts on object and has strenght and direction

1.3.2.2. object's motion can be measured

1.3.3.1. Newton's 3rd law

1.3.3.2. motion of object is the sum of forces acting on it

1.3.3.2.1. E

1.3.4.1. Newtons 2nd law

2. Types of Interactions

2.1. objects must be in contact

2.1.1. Electromagnetism

2.2. Objects do not require to be in contact

2.2.1. Gravitational

2.2.1.1. objects with mass

2.2.1.2. always attractive

2.2.2. electric

2.2.3. magnetic

2.2.3.1. attractive or repulsive

2.3. Strong & weak nuclear interactoins

2.3.1. atomic nuclei

2.4.1.1. objects touch or collide, they push on each other

2.4.2.1. objects in contact exert forceo n each other

2.4.2.2. gravitational force of earth pulls object to planet's core

2.4.3.1. Electric & Magnetic

2.4.3.2. two masses always have gravitational force

2.4.4.1. Newton's law of universal gravitation

3. Stability and Instability in Physical Systems

3.3. system can be changing or with repeat cycle of changes

3.4.1.1. When object moves or stay still it depends on the push and pull on it
