Laws of Nature
1. Gravity:
a. _________ is the natural force that constantly pulls all things to the earth and
affects an object’s weight.
b. ___________________ is a point where the mass of the vehicle is concentrated and
balanced.
c. The higher the center of gravity, the more ___________the vehicle becomes.
d. When a driver _______________________________________________, the G
forces are amplified.
2. Kinetic Energy:
a. Kinetic energy is the energy an object possesses due to its _________, or
__________ (v) and its __________ (m) : KE = 0.5 ∙ m ∙ v2
b. The _________ the object moves, the ______________ it collects.
c. A _________moving object will have ________ kinetic energy than a lighter object
moving at the same speed.
d. A vehicle’s kinetic energy can be overcome by brakes, friction, air resistance and
gravity.
3. Momentum:
a. Momentum refers to the quantity of motion an object has, measured in kg ∙ m/s
b. Formula: p = m ∙ v. The _______ mass and more velocity an object has, the _______
momentum
c. Change in momentum is called impulse; the magnitude of impulse is based on the
amount of opposing force and the time span over which that force is applied.
4. Inertia: an object’s tendency to _____________ any change in its state of motion.
A Vehicle’s
Possible
States of
Motion
• Slowing down or Stopping
• Accelerating or Cruising
• Turning towards the Left
• Turning towards the Right
5. When driving through a curve, inertia creates the sensation that you are being pulled toward
the outside of the curve. Why does this happen?

1. Line-of-sight is the visible path of travel from your vehicle to the target area.
a. When something obstructs your LOS, you may need to ________ your speed and/or
position until it is clear again
1. Path-of-Travel is the series of continuous ____________your vehicle will occupy while
traveling toward your target area
3. Target
a.
b.
c.
d.

Near visual field limit
Steer toward
Changes to whatever appears in the center of your path of travel
** Do ________stare at or fixate your gaze on the target itself…
4. Target Area
a. Rather than focusing directly on the Target, continuously scan to the ____________
of it (the Target Area) for relevant information and potential hazards
5. Lane Positions:
Lane positions are
based upon an average
lane size of 12-feet
wide, and a vehicle 6feet wide
Select the lane
position that gives
you the best line
