Solving for V
D = 8 m
T = 4 s
V = ?
What is 2 m/s?
V = 30 mi/hr
T = 2 hr
D = ?
What is 60 miles?
V = 25 mi/hr
D = 5 miles
T = ?
T = 0.2 hours (12 minutes)
(Note: It's easiest to keep in hours)
This term means speed in a certain direction.
What is velocity?
This phase of the moon will happen tonight.
What is a full moon?
What is 0.25 cm/s?
You walk at a speed of 4 mi/hr. How far did you travel if you walk for half an hour?
What is 2 miles?
If you jog a 5 km race with a speed of 0.125 km/min, how many minutes did the race take you to jog?
What is 40 minutes?
Car A and Car B move the same distance. Car A takes more time to go that distance. Which car is faster?
What is car B?
(Because same distance/smaller time gives a larger speed value)
This is the Spanish word for "moon".
What is "luna"?
This is the average velocity of a car that drove 40 km west, stopped for gas, and then drove another 80 km in a total of 2 hours.
What is 60 km/hr?
This is how far a car will move in 25 minutes (1,500 sec) at a speed of 12 m/s.
What is 18,000 m?
Josslyn calculated the rounded speed of the blue car to be 2.2 m/s. Since the distance of the flag is .01 m, what did the timer box read when she made this calculation?
Car A and Car B take the same amount of time to get somewhere. Car A travels less distance (by taking a "short cut"). Which car is faster?
What is car B?
(Because greater distance/same time gives a larger speed value)
Scientists believe that this planet has 82 moons, which is the highest number of moons in our solar system.
What is Saturn?
This is the instantaneous speed of a blue car on our tracks if it passes through one photogate in .0042 seconds.
What is 2.38 m/s?
This is the total distance you traveled if you moved for 80 sec at a rate of 3 m/s and for 70 seconds at a rate of 2 m/s.
What is 380 m?
If you need to get somewhere that is 90 miles away by 5:00 pm and you can drive at an average speed of 60 mi/hr, this is the latest time you can leave in order to make it on time.
What is 3:30 pm?
This is what "per" means (like in miles per hour).
What is "for each" or "for every"?
Also acceptable: "divide"
This man was the first human to step on the surface of the moon.
Who is Neil Armstrong?
Calculate the average speed of the blue car using what you need from the following data.
Gate A - position 20 cm mark
Gate B - position 40 cm mark
Time at A: .0048 sec
Time at B:.0049 sec
Time from A to B: .0746 sec
What is 268.1 cm/s?
Light travels at a rate of 299,792,459 m/s. How many KILOMETERS away is the Earth from the moon if it takes about 1.28 seconds for light to reflect from the moon to the Earth? (Note there are 1,000 m in a km.)
What is 384,400 km?
This is the number of MINUTES it would take for a cheetah to run 9 miles at a speed of 45 mi/hr.
What is 12 minutes?
This is the physics term for the rate at which your speed changes. (This will be our next topic.)
What is acceleration?
This is what causes a total lunar eclipse.
What is the moon and sun are on opposite sides of the Earth?
or
What is when the Earth comes between the sun and moon which blocks the sunlight falling onto the moon?
