Instantaneous vs Average Velocity
1. Emilio drops a tennis ball from a height of 5 meters above the ground. It takes 1 s for the ball to hi
-5m-5 m/s, and concludes that the
the ground. He calculates the velocity of the ball from v=
1s
ball had a velocity of 5 m/s after it hit the ground.
a. Is Emilio's work correct? Why or why not?
opeb. What is the actual velocity of the ball when it hit the ground?
c. What does the -5 m/s Emilio calculated represent?
Instantaneous vs Average Velocity
When we calculate velocity from v=we are calculating the average velocity which describes the
average motion of an object over a range of time. However, the average velocity of an object does no
plerating object. You can also find the average velocity by
