Q
  1. Write the three formulas for calculating density, mass, and volume using the density triangle
A

Mass= DxV
Density=M/V
Volume=M/D

16
Q
  1. If an object’s density is over 1g/cm3 will it float or sink? What if an objects density is over 1g/cm3
A

Sink

Float

17
Q
  1. If an object’s mass is more than its volume, will it sink or float? If an objects volume is more than its mass, will it float or sink?
A

Sink

Float

18
Q
  1. On a graph which line represents the highest density: steepest or least steep
A

Steepest

19
Q
  1. If ice can float on the surface of water, is it just as dense as water or less dense
A

Less dense

20
Q
  1. Define buoyant force
A

The upward force that keeps an object immersed in or floating on a liquid

21
Q
  1. True or False: Buoyant force works against the downward pull of gravity
A

True

22
Q
  1. What happens to the pressure of a fluid as an object’s goes deeper
A

Pressure increases as depth increases. There’s more pressure at the bottom than the top of the object

23
Q
  1. What is Archimedes Principle
A

The principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces

24
Q
  1. Buoyant force equals the weight of water that is displaced
A
  1. Buoyant force equals the weight of water that is displaced
25
Q
  1. If buoyant force is equal to the weight of the object, then the object will
A

Float within the fluid

26
Q

27.if buoyant force is greater than the weight of the object, then the object will be

A

Buoyed up

27
Q
  1. If buoyant force is less than the weights of the object, the the object will
A

Sink
