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

Distance Distance – how far an object traveled; length

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

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

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

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

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

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

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

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 - 9:30 Δt = 2 hours

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 = 240 mi 4 h v = 60 mi/h or 60 mph

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.
