Forces & Energy (first law of motion (inertia (is the tendency of an…

- - - - to resist change in motion
- - - - when air resistance=gravity
- - - - on the first object
- - - - move/change matter
    - - joule (Newton x meter)
    - - energy stored
        
        result of shape or position
        
        stored energy is
        converted into kinetic energy
      - gravitational potential energy
        
        depends on object's height
        
        depends on its mass, height, and acceleration due to gravity
      - formula: PE (potential energy) = mgh
    - - formula:
        KE (kinetic energy) = 1/2mv^2
        
        m = mass (in kilograms)
        
        v = speed in meters per second
        
        doubling mass would
        double kinetic energy
        
        but doubling speed would
        multiply speed four times
      - (of any moving object)
        depends on its mass and speed
    - - associated with motion and
        position of everyday objects
      - sum of object's potential energy
  - - - power = work/time
      - rate of doing work
        
        faster rate = more power
    - - joule
        (Newton x meter)
    - - over a certain amount of distance
