◉ What are the 3 Natural Laws of Motion?
Answer: Law of Inertia: An object stays at rest, or keeps moving at
a steady speed in a straight line, unless an outside force changes
it.

more force to make it speed up. A lighter object speeds up faster
than a heavy one when you use the same push.
Law of Action and Reaction: For every action, there is an equal
and opposite reaction.
◉ What does a roll do?

◉ What does a Pitch do?
, Answer: A pitch rotates around the lateral or transverse axis and
can act independently of the Roll or Yaw.

Answer: Misuse of Brakes
Misuses of Steering
Distractions
