Semester one notes

Not as many as I thought...
Show Answers:

  1. Length/ distance
    meters (m)
  2. Mass
    Kilograms (kg)
  3. Velocity
    Meters per second (m/s)
  4. Acceleration
    Meters per second squared (m/s2)
  5. Momentum (p)
    kilogram times meters second squared (kg x m/s2)
  6. Force
    Newton (N)
  7. Work
    Jule (J)
  8. Weight
    Newton (N)
  9. Time
    Second (s)
  10. Convert 60km per hour to SI units.
    • 60km = 1km = 1000m = 16.7m
    • 1 h 1 min 1 min 1 sec
  11. Express in scientfic notation: 17,000,000
    1.7 x 107
  12. Express in scientfic notation: .00000089
    8.9 x 10-7
  13. Newton's first law
    • The Law of Inertia:
    • A soccer ball at rest in a field
    • Objects at rest stay at rest: Every object in a state of uniform motion tends to remain in that state of
    • motion unless an external force is applied to it.
  14. Newton's Second Law
    • Force and acceleration
    • Soccer ball being kicked
  15. Newton's Thrid Law
    • Action and Reaction
    • Kayak paddles pushing water
    • For every force there is an equal and opposite reaction
  16. Velocity and Acceleration
    • V: Speed together with direction of motion
    • A: Rate at which velocity is charging. May be magnitude, direction or both.
    • Both are vectors
  17. Law of Conservation and Momentum
    • In the absence of a net external force the momentum of an object or system of objects is unchanged.
    • (Object at rest stays at rest)
  18. Impulse-momentum theorem
    Impulse= change in momentum
  19. Elastic collision
    Two projectiles bounce off each other; apart/ seperation
  20. Inelastic collisions
    Projectiles hit and stick; same velocity after collision
  21. Projectile motion
    Can be vertical or horizontal
  22. Circular Motion
    • Rotation: Object goes around itself
    • Revolution: Goes around something else
