review speed/veloc. lesson

What is speed?

• How slow or fast something goes

• How far or near something is

• How small or big something is

• How difficult or complex something is

Mark the options that are NOT properties of both speed and velocity.

• Magnitude

• Scalar

What is a scalar?

• A unit

• A measure with magnitude but no direction

• A measure with magnitude but no unit

What is a vector?

• A unit

• A measure with magnitude and direction

• A measure with magnitude but no direction

• A measure with magnitude but no unit

Which of these is a vector?

• Speed

• Distance

• Displacement

• Position

What is the SI unit for displacement and distance?

• Liter

• Gram

• Seconds

• Meter

4 hectometers are equal to:

• 400 meters

• 40 meters

• 4,000 meters

• 0.004 meters

What is a frame of reference?

• An object that is moving relative to you and you choose it to detect the motion of other things by comparing them to it

• An object that is not moving relative to you and you choose it to detect the motion of other things by comparing them to it

• An object that can be moving or not relative to you.
