A woman walks 100 m. It takes him 50 seconds to do this. What is the woman's speed?
A dog ran at a speed of 20 m/s for 10 seconds. How far did it travel in this time?
A car decides to get on the freeway and accelerates from 12 m/s to 20 m/s over 4 seconds. What is it's acceleration?
Can you accelerate while traveling at a constant speed?
Yes, by changing the direction in which you travel
No, as long as speed is the same, the acceleration is always zero.
What two factors can create a change in velocity?
Change in speed and a change in time.
Change in direction and a change in time.
Change in speed and a change in direction.
Change in time and a change in direction.
Which of the following is not a unit of velocity or speed?
What does the triangle, delta, mean?
change in speed
change in velocity
change in acceleration
