- 1What does a steep upward slope on a distance vs. time graph mean?A steep upward slope on a distance vs. time graph means the speed is set at a fast, constant pace.
- 2What formula is used to find speed?The formula to find speed is the rate of change of position divided by the period of time.
- 3What is the formula of average speed?The formula for the average speed is the total distance divided by the total time.
- 4A dog runs 40m in 60s. What is the dog's average speed?as=40m/60s as=20m/30s as=2m/3s The speed is 0.67 m/s.
- 5Jenny travels 205 km in 2h. What is Jenny's average speed?as=250km/2h as=125km/s Jenny travels at an average speed of 125km/s.
- 6What is the formula for acceleration?a=v(final)-v(initial)/t(final)-t(initial)
- 7Jeff drives from 100km/h to 25km/h in .5h. What is Jeff's acceleration.a=25km/h-100km/h/.5h-0h a=-75km/h/.5h a=-150km/h/h Jeff accelerates -150km/h/h.
- 8A sailboat accelerates from a rest to a velocity of 25km/s in 8 s. What is the acceleration?a=25km/s-0km/s/8s-0s a=25km/s/8s a=3.13km/s The sailboat accelerates 3.13km/s.
- 9What is the formula to find distance given speed and time?The formula is d=vt.
- 10A cat can run an average speed of 4m/s. How much time will it take the cat to run 120m.t=d/t t=120m/4m/s t=30s A cat takes 30s to run 120m.
- 11Motion is a change in ___________.position
- 12Define constant speed.Constant speed is traveling the same distance every second.
- 13What does the slope of the line on a speed-time graph tell you.The slope tells you the acceleration over the given time.
- 14You are traveling down the sidewalk at 2m/s. You continue at this speed as you turn down the next street. Did you accelerate? Why or why not?You do accelerate because acceleration includes speeding up, slowing down, or changing direction.
- 15What are the three ways in which an object can accelerate?The three ways an object can accelerate is by speeding up, slowing down, or changing direction.
- 16Define and give an example of instantaneous speed.Instantaneous speed is speed in a specific interval. EX: From 3s to 6s, the marble rolled 7cm/s.
- 17What type of graph is used to show acceleration?The type of graph you use to show acceleration is speed vs. time.
- 18What type of graph do you use to show speed?The type of graph you use to show speed is a position vs. time graph.
- 19What are some possible units for distance?mm
cm
m
km
mi
y - 20What is the normal unit for acceleration?m/s(squared)
- 21What are some possible units for speed?mm/s
cm/s
m/s
km/s
y/s
mi/h
km/h
etc... - 22What are some possible units for time?s
m
h - 23How can you use rise and run to find the slope of a graph? What is the rise? What is the run?The rise is the amount you go up on the y-axis. The run is the amount you go up on the x-axis. To find the slope, you do y2-y2/x2-x1
- 24If a graph has a rise of 500m and a run of 10min, what is the slope? Include units!v=500m/10min v=50m/min
- 25On a speed vs. time graph, how would constant velocity appear.The line would be straight.
- 26Read this statement: A train is traveling 60km/h north. This statement describes the train's what?velocity
- 27Define acceleration.Acceleration is the rate at which the velocity changes over time.
- 28What is the difference between speed and velocity?The difference between speed and velocity is speed includes the distance over time and velocity includes both speed and direction.
- 29If you know the time and the speed a jet has traveled, how could you find the distance traveled?d=vt
- 30What are the units for the axis on a speed-time graph? What does this graph show?0 acceleration
- 31What are the units on a distance-time graph? What does this graph show?Increasing speed
