Balanced and unbalanced forces - Coggle Diagram
Balanced and unbalanced forces
Inertia
it is hard to start but easy to keep goin
Crash testing
different heights make it go faster
weight
if it is heavy it has more
if it is light it has less
Speed
Metres Per Second
distance/time
affects crash testing
more is better in races
Crash Testing
Seatbelts
injury
inertia
crumple zone
Friction
marble
gravel
decking
grass
how much energy is needed to push something along on a surface
balanced force
equal
no movement
drag=accel
gravity = lift
Unblanaced Force
movement
drag != accel
gravity != lift
Types of forces
drag is back
acceleration is forward
gravity is down
lift is up
ticker tape timer
50 ticks a second
measure speed
make a graph
10 ticks = 0.2 seconds
Newtons Laws
Force = Mass * Acceleration
For every action that occurs there will be an equal opposite reaction
if something is still it will not move until pushed
and it will not stop until something stops it
