Newtons Third Law Flashcards
What is inertia?
The tendency for a motion to remain unchanged
What is inertial mass?
How difficult it is to change the velocity of an object
How do you rearrange newtons second law for inertial mass?
M = f/a
What is newtons third law?
When two objects interact the forces they exert on eachother are equal and opposite
What is the formula for momentum?
Momentum = mass x velocity
What is conservation of momentum?
The total momentum before and after an event in a closed system is equal
How do you find force with change in momentum and time
Force = change in momentum / time
Is a change in momentum occurs quickly what will happen to the force
It will get bigger
What can affect thinking distance?
Fatigue alchohol drugs and distractions
What can affect braking distance?
Speed, mass of vehicle, brake conditions and road condition
What is equal to a vehicles energy store?
