Flashcards in P2 Physics - Braking and stopping distances, terminal velocity Deck (7)
what is thinking distance
distance travelled in between the driver realising he needs to brake - and actually braking
what is braking distance
distance taken to stop once brakes are applied
what is terminal velocity
the constant speed at which a free falling object reaches when resistance allows it not to accelerate anymore
what is elastic potential energy
objects can store elastic energy if stretched or squashed
when a spring is stretched what is the increased length called?
what does F = k x e mean?
F = force in newtons
k = spring constant
e = extension in metres
