Speed or Velocity?Speed –
the rate at which an object moveshow fast an object moves15 m/s (meters per second)
Velocity – an object’s speed in a specific direction
how fast AND which way an object moves
5 m/s north

Fill in the triangle with the formula for speed.
What is the velocity of a car that traveled 252 miles East in 4
hours?

Acceleration
• Acceleration – The rate at which velocity changesA change in velocity
(Speed or Direction)
Examples:Speeding up- A plane taking offSlowing down- A car stopping at a red lightChanging direction – A car turning at a corner

Warm-UpAug. 29,2011
What two factors determine an object’s speed?
Practice Problem:What is the velocity of a runner traveling 35 meters North in 7
seconds?
Distance and Time
Speed = Distance Time
= 35 m 7 s
= 5 m/s
