speed distance time
Speed, Distance, Time
  • Speed is a scalar quantity. A quantity that has only magnitude. (a number plus a unit)
  • For example: 10 mi/h, 12 km/h, 5 m/s
  • Average Speed: The ratio of the total distance divided by the time.
  • Average Speed = distance / time
velocity displacement time
Velocity, displacement, time
  • Velocity is a vector quantity. A quantity that has both magnitude and direction. (A number, a unit, and a direction)
  • For Example: 6.5 m/s, East
  • Average Velocity: The ratio of the change in position to the time interval during …
  • v(ave) = displacement / time
  • displacement = d(f) - d(i) OR d - d(o)
acceleration v time
Acceleration, /\v, time
  • Acceleration is a vector quantity. A quantity that has both magnitude and direction
  • For Example: 12 mi/h/s, East and
  • +3 m/s/s which means 3 m/s/s forward
  • Average Acceleration: The change in average velocity divided by time
  • Acceleration = /\v / t
  • And /\v = v(f) - v(i) OR v - v(o)
what s up with m s s
What’s up with m/s/s?
  • A unit of acceleration is a change in velocity (I.e. m/s) divided by time (I.e. s)
  • When a fraction like m/s is divided a value like s, the rule says to invert and multiply
  • So a unit like m/s/s may be written as m/s^2, where the m/s is being divided by the second, and because of the invert and multiply rule for fractions its m/s^2
working with ps 3 1
Working with PS#3-1
  • Let s represent speed, v(ave) may be used
  • 1a-e, s = d / t
  • 2a-e, d = s * t
  • 3a-e, t = d / s
  • 4a-e, v(ave) = d / /\t, bold type = vector
  • 5a-e, /\t = d / v(ave)
  • 6a-e, d = v(ave) * /\t
working with ps 4 1
Working with PS#4-1
  • 1a-e, a(ave) = /\v / /\t
  • 2a-e, /\v = a(ave) * /\t
  • 3a-e, /\t = /\v / a(ave)
  • 4a-e, a(ave) = [v - v(o)] / /\t
  • 5a-e, v = a * /\t + v(o)
  • 6a-e, v(o) = v - a * /\t
