lesson 8 - Position and Motion

What is a reference point?

• A place or object that is staying still, that is used to determine if something else is moving.

• A place or spot where something is located

• The action of moving or being moved

• Shortest distance between starting position and ending position

Motion can be described through a change in _____.

• temperature

• distance

• position

• speed

20 km/hr is an example of

• direction

• velocity

• speed

• distance

300 km/hr North is an example of

• Velocity

• Speed

• Direction

• Reference point

If you leave home and travel a million miles around the world and stop back home, what is your displacement?

• One million miles

• 0

• two million miles

• none of the above

The graph shows Ashley riding her bike to Maria's house.

What was occurring from point B to point C?

• She was increasing her speed.

• She stopped for 4 minutes

• She was decreasing in speed

• She was moving forward at a steady 800 m/s

Match the description to the graph:

"The car is coming back."

• 
• 
• 
• 

What is the speed of segment B?

• 0.5 m/s

• 2 m/s

• 3 m/s

• 0 m/s

Displacement is the difference between your

• reference point and reference direction

• total distance traveled

• starting position and your final position

• average speed

Which line on the graph represents the fastest constant speed?

• A

• B

• C

• They are all moving at the same speed.
