Which of the following measurements are SCALARS?
Check ALL that are scalars!
Density (kg/m3) of gold
Speed (m/s2) of your car
Distance (m) to KMIDS
Velocity (m/s2) of a tropical storm
Mr. Adam leaves his house at 5am to walk to KMIDS. He has to walk 30km to get to school from his condo. Half way to the school, he realizes he forgot his favorite pencil, so he decides to walk back to his condo. He then gets his charger and walks straight to KMIDS and arrives at 10am.
What is his average speed and average velocity? Assume the walk from KMIDS to Mr. Adam's condo is a straight line.
12 km/hr, 12 km/hr
9 km/hr, 6km/hr
9 km/hr, 12 km/hr
12 km/hr, 6 km/hr
What variable is used to represent position, which is used to calculate displacement?
a
v
d
x
What is the difference between speed and velocity?
Velocity is just the scientific term for speed. They are the same.
Speed has direction whereas velocity does not.
Velocity has direction whereas speed does not.
Speed is measured in m/s whereas velocity is measured in m/s2
When you are driving your car and you look at your speedometer, this is a measure of your ____________.
Average speed
Average velocity
Instantaneous speed
Instantaneous velocity
Which of these are NOT appropriate units for acceleration?
m / s per s
m / s2
m / s
km / hr2
You take your dog to the park. During the walk your dog takes many side trips to smell the tree, pee on the bush, bark at the cat, etc, but he always comes back to you.
At the end of your walk, which of these is TRUE?
You both have the same displacement, but your dog has walked a greater distance.
You both traveled the same distance and have the same displacement.
You both walked different distances, but it is impossible to say which one is greater.
You have both walked the same distance, but your dog has walked a greater displacement.
Keekead Tower in central Silom is slowly moving due to the softness of the ground and a weak foundation. Bobo and Martin are measuring the displacement over the last year and using it to create a model.
BoBo measures the displacement to be - 5cm, whereas Martin measure the displacement to be +5cm. What is one possibility for the difference in their measurement? Choose the BEST answer.
BoBo doesn't know how to measure.
BoBo is measuring distance whereas Martin is measuring displacement.
They are using different frames of reference.
Martin doesn't know how to measure.
What is the displacement of the green dot? (assume measurement in meters)
4m
-4m
12m
-12m
A scalar has _____________, whereas a vector quantity has ___________.
only magnitude, magnitude and direction
magnitude and direction, only magnitude
only a number, a number and the unit
a number and the unit, only a number
