Mass, Weight & Density

Question 1

What is every object pulled toward the earth by?

Answer 1

Gravity

Question 2

What is gravity also called?

Answer 2

Weight (greater the mass the greater the force on it)

Question 3

What is the strength of gravity?

Answer 3

10 N/kg

Question 4

What does 1kg equal in newtons?

Answer 4

10 Newtons

Question 5

What is mass?

Answer 5

It tells us about the amount of matter the object contains

Question 6

What is volume?

Answer 6

It tells us how much space the object takes up.

Question 7

What is density?

Answer 7

It tells us the mass of 1cm3 of a material.

Question 8

Formula for mass volume and density

Answer 8

M
D V

Question 9

How to convert g/cm3 to kg/m3

Answer 9

Time by 1000

Question 10

What is the spacing of solid liquid and gas atoms?

Answer 10

Solid - close together and regular
Liquid - close together and irregular
Gas - wildly spaced

Question 11

Level of kinetic energy and movement in solids liquids and gases

Answer 11

Solid - atoms only vibrate
Liquid - atoms have some KE energy
Gas - atoms move rapidly colliding

Question 12

What is the density and structure of solids liquids and gases?

Answer 12

Solid - fixed structure and denser materials
Liquid - not fixed, take container shape and similar density to solid
Gas - fills the available space. Very low density

Question 13

Weight definition

Answer 13

Force of gravity on a mass
