Identify what must change if the reference point is changed. When a reference point is changed, the description of the___?____ and the ___?____ to the object also must be changed. Select two.

• direction

• position

• distance

• motion

reference point

• the process of changing position.

• an object’s distance and direction from a reference point

• the starting point you choose to describe the location, or position, of an object.

position

• a measure of the distance an object travels in a given amount of time.

• an object’s distance and direction from a reference point.

• a measure of the change in velocity during a period of time.

motion

• the process of changing position

• contact force that resists the sliding motion of two surfaces that are touching

• a quantity that has both magnitude and direction

displacement

• the combination of all the forces acting on an object.

• the difference between the initial, or starting, position and the final position.

• a measure of the distance an object travels in a given amount of time

Displacement is the difference between your

• the middle position

• starting position and your final position

• average speed

You ride your bike 10 miles East but then head West for 6 miles. What is your displacement?

• 6 miles East

• 4 miles East

• 4 mile West

An object's location or _______________ is the distance from a reference point.

• distance

• position

• acceleration

If the reference point is your home and you travel 5 miles to get to Lake Geneva and then come back home, what is the total distance traveled?

• 5 miles

• 25 miles

• 10 miles

When the car reaches point X on the SECOND lap what distance has it traveled

• 2100 m

• 1800 m

• 500 m
