Distance traveled per unit of time
What is speed?
Acceleration?
S = 5 m/s
t= 5 s
What is 1 m/s/s?
Average rate an object is moving over time.
What is average speed?
The acceleration of a car that travels in a straight line at a constant speed.
What is 0 m/s2?
A runner covers the last straight stretch of a race in 4 s. During that time, he speeds up from 5 m/s to 9 m/s. The runner’s acceleration in this part of the race.
What is 1 m/s/s?
The unit of acceleration if the speed is in km/h and the time is in h.
What is km/h2
You are traveling in a car that is moving at a velocity of 20 m/s. Suddenly, a car 10 meters in front of you slams on it’s brakes. At that moment, you also slam on your brakes and slow to 5 m/s. Calculate the acceleration if it took 2 seconds to slow your car down.
What is -7.5 m/s/s?
