3rd law #
Every action is equal and opposite reaction
Force (N) = mass(kg) x acceleration (m/s/s) #
1st Law
An object that is travelling at a constant speed or stationary will remain in that motion unless acted upon by a net force
not force cause acceleration
inertia #
absorbs the impact of the crash
inertia
Speed in a given direction
increases collision time
action-reaction pairs
Prevents whiplash #
decreases force
Prevents upper body or head striking car interior during a collision
Loose objects
more force required to move more mass by same acceleration
Forces don't cancel each other out
continue travelling at same speed car was travelling at
Speed
Average Speed
Total distance travelled / time taken
Instantaneous Speed
Specific speed at a given time
scalar quantity
Magnitude
units
km/h
m/s
Acceleration #
Average Acceleration
Formula
speed final - speed initial / time
units
m/s/s
postive
negative
accelerate
Decelerate
If a Net force is 0 then an object is stationary
