7-1: Motion

A place or object used for comparison to determine if another object is in motion is called a

• comparison point
• reference point
• point of view
• motion detector

The best reference points are stationary (not moving).

• true

• false

The SI (metric) unit for length or distance is

• foot (ft)

• inch (in)

• mile (mi)

• meter (m)

How many meters are in a kilometer?

• 0.1

• 10

• 100

• 1000

an object's distance and direction from a reference point

• position
• motion
• displacement
• reference point

the process of changing position

• motion
• reference point
• acceleration
• speed

Which of the following describes distance and displacement correctly?

• The blue arrow shows distance and the orange arrows show displacement
• The blue arrow shows displacement and the orange arrows show distance
• Both arrows show distance only
• Both arrows show distance and displacement

Displacement is distance combined with

• direction
• speed
• velocity
• magnitude

The object's overall change in position

• Reference Point

• Distance

• Displacement

• Position

Length of path between two points

• Reference Point

• Distance

• Displacement

• Position
