What is the SI Unit for measuring distance
Meter
What ratio compares time to distance traveled?
Speed
This is a quantity that has both magnitude and direction
Vector
Why would it bennificial for a zookeeper to know a lion's velocity if it were to escape from a zoo
To know the direction of travel and how fast it was moving
What is the average speed of Usian Bold when he ran the 200meter dash in 19.19 seconds
10.42 m/s
You notice throughout the day the sun moving across the sky. What is the frame of reference in this scenerio?
the SKY
This is the shortest, strait line distance between two points.
Displacement
What is the instantanious preed of a car that travels from Harrisburg to Wilkes Barre if the car has an average sped of 33mph
Can not be determined
If a car is moving in Uniform Motion, What do we know about the car
Its moving at a constant velocity
How far has a bus traveled if it has been moving at an average speed of 45 mph for 3.5 hours?
157.5 mile
What is the total distance traveled divided by the time it takes to travel that distance?
Average Speed
How is velocity different than speed
They are the same but Velocity tells you the direction of travel.
What do we call the movement of an object toward the Earth when gravity is the only force acting on the object
Free Fall
what do these symbols mean
Final velocity and initial velocity
what is the acceleration of an object that changes its velocity by 8m/s over a time of 5 seconds
40 meters
You are riding on a school bus and look out the window to see the trees zipping by. The tree lets you know you are in motion and are therefore a ______________.
Vector
What do we call the rate at which velocity changes
acceleration
What do we call an obkect falling towards the Earth that reaches its maximum speed
Terminal velocity
What is the calculated accelration of an object in free fall due to gravity
9.8 M/S2
What is the difference between average speed and instontanious speed
Average is over a period of time. Instant is at one particular point in time
What is this symbol mean
Change in velocity
This is acceleration in a negative direction
decelleration
what kind of acceleration occurs when a car steadily increses its speed by 9 m/s every second
constant acceleration
In a vacuume, a golfball and a shot put are dropped from the same height at the same time. Which will reach the ground first. EXPLAIN your answer
Both at the same time because gravity is the same and there is no air resistance to slow the object in freefall.
How far appart are Denver and Buffalo if it takes 4 hours to tavel between the cities at the average speed of 425mph.
1700 Miles
