Forces And Motion Flashcards
Acceleration 2
Final Velocity - Initial Velocity / Time
Objects accelerating at constant rate
V2-U2=2as
Final V - Initial V = 2 acceleration Distance
What is Scalar
No Direction Only Size
I.e: Mass , Temp
What is Vector
Have direction and size
I.e: Displacement , Momentum
Terminal Velocity
Object Stops accelerating moves at constant Velocity
Elasticity
Elastic Materials will always return to their original length if we take away forces acting on them
Elastic Deformation
Materials return back to its original length after being stretched
Inelastic Deformation
Materials does not return to original shape
Acceleration Equation
Change in velocity/ Time
Inertia
Tendency for an objects motion to stay constant if no force
Newtons 1st Law
If no resultant force acts on an object its motion will be constant
Newtons 2nd Law
Acceleration of an object is proportional to force applied
Inversely proportional to mass of object
Newtons 3rd Law
For every action there is an equal opposite reaction
Stopping Distance
Thinking Distance + Braking Distance
Properties affecting Thinking Distance
Speed
Distractions
Alchohol
Drugs
Tiredness
