A student walks 6km South, 4km West and 6km North. What is their total distance?

• 4 km

• 10 km

• 14 km

• 16 km

All of the following are base units of the SI system except:

• kilogram

• kelvin

• meter

• volt

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

Which box has a higher density?  

• Box A
• Box B
• cannot be determined
• they are the same

Using the picture, tell me which object is the least dense and why?

• The fish because he is in the middle

• The cork because it is floating at the top of the water

• The rock because it is at the bottom

• The cork and the rock because they have the same about of atoms.

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.
