Positive
A student walks down the 10 m west down a hallway, and remembers they forgot their calculator and walks 25 m east back to their classroom. What is their displacement?
15 m east
What is the speed of a ball moving 50 meters in 10 seconds?
s = d/t = (50 m) / (10 s)
s = 5 m/s
Speed and velocity are the same
false
How many hearts does an Octopus have?
4
What is the velocity of a ball when is thrown 5 m up in the air and lands on the ground?
Velocity = 0 meters
If a a measurement on an object's movement has a line with a negative slope, what can you assume about it's velocity?
Negative slope = negative velocity
What is Bob's final velocity if he walks 3 m/s east for 20 feet to the refrigerator, then 3m/s west for 10 feet to the couch?
+3 m/s east
Speed is measured in miles per second
false

A car is measured to be moving at 20 meters in 5 seconds and stops for 10 seconds. What is the car's velocity the last 4 seconds of measurements?
0 m/s
Angela walks in a straight line around the globe and ends where she started. What is her velocity?
Velocity is shown as a magnitude with a direction
True
What is the name of the element that glows in the dark due to chemical reactivity.
Phosphorus
A car's velocity is -60 miles per hour. Would the direction be north or south?
South
What is the slope of the following velocity? --> 15 m/s
Positive, negative, or 0 (zero)
Positive slope
A car travels 150 miles east from point A to point B in 3 hours, then returns west to point A in 5 hours. What is the car's average velocity for the entire trip in mi/h?
0 m/h

Seoul
At 2 seconds and objects position is at 6 meters.
1 seconds later the objects position is recorded at 5 meters. What is it's velocity?
-1m/s
What final position of a bullet that starts at a position of 10m, has a velocity of 800 m/s, and travels for 1.2 seconds?
d = S (t) = (800 m/s) (1.2 s) = 960 m
since position started at 10 m --> 960 m + 10 m = 970 m
How many hours would it take for a car to travel 150 mi moving at a constant speed of 60 mph?
t = d/s = (150 mi) / (60 mph)
t = 2.5 hours
On a position-time graph, position is located on the y-axis
True
