Name the different 2 types of forces and give two examples for each.

Contact and non-contact


Contact: friction, air resistance, upthrust


Non-contact: magnetism, gravity

Cancelling...


Cancelling...

What is a balanced and unbalanced (resultant) force

Balanced= when forces cancel each other out.


Unbalanced=when a force overpowers an opposing force.

Arrows and strength...

How do we measure volume?


In what unit?

Get set amount of water, put object in, measure increase. Exp, 100ml of water,put object in, 600ml of water, object has 500ml of volume.

Eureka!!! Displacement... Blocks...

What is mass measured in?


What is weight measured in?

Weight-newtons


Mass-kg,g

Qi claxon...

How is mass calculated?

Weigh it

Scales...

How do you work out density?

D=M÷V


Density=mass ÷volume

M over V

How do you measure weight?

W=M×G


Weight=mass ×gravitational field strength

M and G
