An object is in _____ any time its position is changing.

• motion
• distance
• speed
• time

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

In order to determine an object’s location, you need a _____.

• time

• displacement

• speed

• reference point

To determine if an object has changed position, you need to know its position relative to another object. _______________

• True

• False

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

What is the difference between distance and displacement?

• distance is the total length of the path an object travels. Displacement is the straight line distance from starting point to ending point with a certain direction
• displacement is the total length of the path an object travels. Distance is the straight line distance from starting point to ending point.
• displacement uses no direction whereas distance does
• there is no difference. they are the same!

North, south, east, west, right, left, up and down are all words used to describe _____.

• direction
• motion
• position
• speed

What is displacement?

• how far an object is from it's starting point

• the total length of an object's path

• weight that is displaced from a body of water

• the change in an object's path

What is the displacement from HOME to SCHOOL in this image?
