1.2 Uniform Motion

A vector quantity has...

• magnitude but no direction

• direction but no magnitude

• neither magnitude or direction

• both magnitude and direction

True or false? Position is a vector quantity.

• True

• False

True or False? Displacement is a vector quantity.

• True

• False

Speed is to distance as velocity is to...

• position

• displacement

• instantaneous speed

A cat runs 52 m [E] from a tree. If the tree is 6 m [W] of a house, what is the cat's position relative to the house?

• 58 m [E]

• 46 m [E]

• 58 m [W]

• 46 m [W]

Your dog runs 17 m [N] to get a ball then returns it to you. His displacement is:

• 17 m [N]

• 17 m [S]

• 34 m

• 0 m

In a rock-climbing competition, your friend climbed up 325 m in 5 minutes. What was her velocity?
