100
What vocabulary word is the change in an object's position relative to a reference point?
Motion
100
In what three ways does acceleration change?
Direction, slowing down, speeding up.
100
60 mph is an example of what
speed
100
Which segment was the biker farthest from home?
D
100
What is the difference between instantaneous speed and average speed? Give an example of each
Instantaneous speed is knowing the speed of an exact moment-Speedometer.
Average speed is the total speeds divided the length of time.- The average speed of our trip to Florida was 50mph
200
How do displacement and total movement differ?
Displacement is how far away you are from the starting point. Total movement is all movement added together, whether it be farther or closer to the starting point.
200
Why does a rubber band not travel horizontally forever and ever?
Gravity
200
60 mph south is an example of what
Velocity
200
On a distance-time graph, what goes on each axis?
x- Time
y-Distance
200
If a runner maintains a speed of 2mph, how long would it take for the runner to complete 22 miles?
11 hours.
300
What vocab is the distance an object travels per unit of time?
Speed
300
What are the SI units for speed, acceleration and velocity?
m/s, m/s^2, m/s
300
35 m/s2 is an example of what
Acceleration
300
Segment A-B, 10 m/s
300
Give me the formula for acceleration.
Final velocity minus initial velocity all over time interval.
400
What is the slight difference between speed and velocity? How are speed and velocity similar?
Velocity also states direction, but both speed and velocity state unit of time.
400
What is the formula for speed?
s=distance/time
400
If a car is slowing down, what is happening to acceleration and velocity?
Acceleration is negative and velocity is forward.
400
Slope= 4/2=2
400
Sorry....I couldn't think of anymore questions....so.....
You just lost 100 points :( *tear*
500
What is the definition of momentum and what variable represents momentum?
Is the product of an object's mass and velocity.
500
What is the acceleration toward the center of a curved or circular path.
Centripetal acceleration.
500
What is the momentum of a 5kg pig running at a speed of 15m/s?
5kg*15m/s= 75kg.m/s
500
Convert 35 km/h to m/s
500
From the starting line, I took off running and had a speed of 20 meters per second. If the race was only 10 seconds long, what was my acceleration?
2 m/s2
