Mapping Motion
This term describes a change in an object’s position over time.
What is- displacement? (Acceptable: What is Motion?
Formula for calculating average speed.
What is distance over time (s=d/t)?
Speed is just a rate of motion, while this vocabulary word describes both an objects speed and direction
What is- Velocity?
Formula for acceleration.
A = Δ v / Δ t
Formula for momentum.
What is: p=mxa
The object or location used to determine if motion has occurred.
What is- a reference point?
An Olympic runner runs 100 m in 10 s, what’s their speed in m/s?
What is: 10 m/s?
If a car moves 50 m east in 5 s, what is its velocity?
What is: 10m/s East
A car speeds up from 10 m/s to 20 m/s in 2 s. What is its acceleration?
What is: 5m/s2?
What two factors affect an object’s momentum?
What is- mass and speed?
If your distance changes but you end where you started, what is your displacement?
What is: 0?
This kind of speed describes motion over an entire trip, unlike instantaneous speed, which measures one specific moment.
What is: average speed?
Even if an object is moving at a constant rate, it can still change its velocity by...
What is- direction?
A line sloping upward on a speed–time graph shows what type of motion?
What is Acceleration (speeding up)
If an object’s speed doubles, what happens to its momentum?
What is- it doubles?
The total length an objects path over a period of time
What is- distance?
You travel 60 km in 2 hours. What’s your speed?
What is: 30 km/h?
You travel in a circle at a constant speed — is your velocity constant?
No
If a car slows down, its acceleration is __________.
What is- negative?

What is - the bowling ball?
What does a flat (horizontal) line on a distance–time graph mean?
What is- no motion?
What type of speed is shown on a car’s speedometer?
What is- instantaneous speed?
This type of graph is used to show how objects speed changes over time?
What is- a velocity- time graph?
What does the area under a speed–time graph represent?
What is- the distance traveled?
Which has more momentum — a 1,000 kg car at 5 m/s or a 2,000 kg truck at 2 m/s?
What is- they are equal?
