1. QOD#
What is the motion of the bat swinging and the ball moving when a baseball player hits a homerun? Bat swing – circular or oscillating (depending on the swing) Ball moving – projectile & linear

2. Distance
Distance – how far an object traveled; length

3. d = 20 m – 5 m d = 15 m Ex1: d = final - initial
0 m 5 m 10 m 15 m 20 m

4. d = 35 mi – 15 mi d = 20 mi Ex2: d = final - initial
0 mi 10 mi 20 mi 30 mi 40 mi

5. Ex3: Sarah starts her drive at the 35 mile marker
Ex3: Sarah starts her drive at the 35 mile marker. She finishes her drive at the 80 mile marker. What is the distance she traveled?
d = final – initial
d = 80 mi – 35 mi
d = 45 m

6. Ex4: Paul’s car odometer reads 120 miles in his driveway
Ex4: Paul’s car odometer reads 120 miles in his driveway. When he arrives at work it reads 147 miles. What is the distance he travels to work?
d = final – initial
d = 147 – 120
d = 27 miles

7. Speed t = tfinal - tinitial
Speed – the distance traveled in a certain amount of time. Speed equation: v = d t
Variables:
v = speed/velocity
t = time
t = tfinal - tinitial

8. Speed of Classmates
Student
Distance
Time
Speed in m/s
10 m

9. QOD#87
Brad’s boat travels from the 3.5 mile marker to the 5.5 mile marker on Mississippi River. What is the distance the boat traveled? d = xf = xi d = 5.5 mi – 3.5 mi d = 2 mi

10. Ex1: A car left the house at 9:30 am and arrives at 11:30 am
Ex1: A car left the house at 9:30 am and arrives at 11:30 am. How long did the car drive?
Δt = tf - ti
Δt = 11: :30
Δt = 2 hours

11. Ex2: A car travels 240 miles in 4 hours
Ex2: A car travels 240 miles in 4 hours. Find the speed the car traveled.
v = d Δt
v = mi
4 h
v = mi/h or
60 mph

12. QOD#88
Zach runs 3 miles in 0.5 hours. How fast did he run in mph? How fast did he run in miles/minutes? v = d / Δt v = 3 mi / 0.5 h v = 6 mph
v = 3 mi / 30 min
v = 0.1 mi/min.
