Speed
Define Speed
How fast an object moves.
Define Velocity
Describes a change in speed or direction or both.
Define Acceleration.
Acceleration is the change in velocity's rate (speed or direction).
Miles races the go cart around the 200 meter track in 25 seconds. What is his speed?
S = D / T
S = 200 m / 25 s
S = 8 m/s
What is the name of the wizarding school Harry Potter attends?
Hogwarts School of Witchcraft and Wizardry.
What is the equation for calculating speed?
Speed =Distance/Time (S = D/T)
What is the formula for velocity?
V = Distance/Time = D/T
What are the two kinds of acceleration?
Positive acceleration and negative acceleration (deceleration)
Connor threw a pitch from 60 feet to home plate 1.8 seconds. What speed did he throw the pitch at?
S = D/T
S = 60 feet / 1.8 seconds
S = 33.33 f/s
What is the only letter that doesn't appear in any U.S. state name?
Q
How is speed measured?
Distance measurement/Time measurement
Examples: miles/hour, meters/second
How is velocity measured?
Distance traveled/Time elapsed followed by Direction
Example: 60 miles/hr North
The direction MUST be listed to show that velocity is being measured.
What is the formula for calculating acceleration?
A = final velocity - initial velocity/time
A = Vf - Vi/time
V = D / T
D = V x T
D = 80mph x 5 hours
D = 400 miles NORTH
Which popular Netflix series features a group of kids trying to solve mysteries in their town?
Stranger Things
Miles runs 125m in 22s. What is his average speed?
S = D/T
S = 125m/22s
S = 5.68 m/s
What is the thing that makes velocity different from speed?
It includes direction.
Usain Bolt achieves a velocity of 15 m/s in 9 seconds. What is his acceleration?
A = Vf - Vi/time
A = 15m/s - 0 / 9
A = 15/9
A = 1.67 m/s
Terrica finishes a 400 m race in 56 seconds. What was her speed?
S = D / T
S = 400m/56s
S = 7.14 m/s
How many teeth do most adult humans have?
32
Justin needs to deliver a Shipt order to a location that is 180 miles away. How fast does he need to drive to get the delivery done in 3 hours?
S = D/T
S = 180mi/3 hours
S = 60 mi/hr
V = D/T
V = 250 meters/ 91 seconds
V = 2.75 m/s north
A Mercedes accelerates from a standstill to 60mph in 2.8 seconds. What is the Mercedes acceleration?
A = Vf - Vi/time
A = 160mph - 0mph / 2 hours
A = 160mph/2hr
A = 80 mph
Justin accelerated from 20 m/s to 55 m/s on the highway in 13 seconds. What was his acceleration rate?
A = Vf = Vi / Time
A = 55m/s - 20m/s / 13s
A = 35m/s / 13s
A = 2.69 m/s
What does the French phrase “Bon Appétit” mean?
"Enjoy your Meal"
