Forces
How can forces effect an object
Shape
Speed
Direction
Newtons 3 laws of motion
Newtons 2nd law- F=ma
Newtons 3rd law of motion- for every action there is an equal and opposite reaction.
Newtons 1st law-an object remains in the same state of motion unless a resultant force acts on it.
Name the 2 types of forces
Push
Pull
The difference between balanced and unbalanced forces
Unbalanced
Moves/changes speed
Resultant force
Balanced
In equilibrium
All the forces are equal
Presure
Why is the pressure higher the further underwater you go
Their is more weight from the water above you
p=f/a (pressure =force/area)
What is friction
Friction is a force that often emits thermal energy. Examples of friction are water resistance and air resistance
Speed=distance/time
