Motion part 2

Motion

Reference Point
1. Static
  1. If the reference point is at rest.
2. Moving
  1. If the reference point is in motion.
3. Measured in terms of distance in regards to the body being measured.
Displacement
1. Speed
  1. Distance divided by time
  2. M/S
  3. Velocity
    1. Speed with direction
2. Distance
  1. Si unit: Metres (M)
3. Time
  1. Si unit: Seconds (s)
4. Acceleration
  1. Rate of change of velocity
  2. Si unit: Metres per second squared (m/s^2)
Newtons Laws
1. 1st Law
  1. Law of Inertia
    1. Objects at rest, will remain at rest
    2. Objects in motion, will remain constant in motion
      1. All bodies at rest or in motion, will remain in that state unless another force acts upon it
2. 2nd Law
  1. Law of Acceleration
    1. Applying an equal amount of force to object A, which is heavier, will cause it to accelerate more slowly.
    2. Applying and equal amount of force to object B, which is lighter, will cause it to accelerate more rapidly.
    3. Acceleration is the direct affect of force exerted on a body, and of its mass.
3. 3rd Law
  1. Law of action and reaction
    1. For every action, there is an opposite reaction
Movement
1. Simple
  1. Moving in simple movements such as travellinng in a straight line.
2. Complex
  1. Complicated movements such as circular motion, where forces act on angles.
Reference Frame
1. The instant frame in time in which the body will be measured.
