what are the 3 newtonian laws - CORRECT ANSWERS 1. every body at rest tends to remains
at rest, while every body in motion tends to remain in motion until acted upon by
unbalanced external force (also known as inertia or centrifugal force
2. the acceleration of a body is propertional to the force applied and inversely propertional
to the mass of the body. (this is teh law of acceleration) the force exerted on an object is
equal to its mass times acceleration.
3. for every action force there is an equal and opposite reaction force. (this is the law of
conservation of energy: momentum)
definition of force - CORRECT ANSWERS energy that causes or alters motion
types of force - CORRECT ANSWERS 1. centrifugal force (outer)
2. centripetal force (center)
3. inertia
4. momentum
5. velocity
6. gravity
7. friction
Centrifugal force - CORRECT ANSWERS an increase in centrifugal force which impels an
object outward from the center of rotation
Centripetal force - CORRECT ANSWERS opposite of centrifugal force; pushing toward the
center
definition of inertia - CORRECT ANSWERS resistance to motion, action, or change
definition of momentum - CORRECT ANSWERS the greater the speed or mass, the more
time and distance needed to effect a stop
definition of velocity - CORRECT ANSWERS 1. the rate of change of position relative to time
2. speed of motion in a particular direction
3. velocity- having both magnitude and direction

definition of friction - CORRECT ANSWERS the force between 2 bodies that resists motion
3 types of energy - CORRECT ANSWERS 1. potential - corners
2. kinetic - when we are going forward
3. static (holds vehicle to ground)
vehicle dynamics / stable platform - CORRECT ANSWERS vehicle is most stable when @ rest
or when moving in a straight line @ a constant speed on a paved level service.
Vehicle stability - CORRECT ANSWERS -occurs with three driver inputs: acceleration,
braking, steering, deacceleration, de-breaking
you should never drive between what of your ability - CORRECT ANSWERS 90-95%
weight transfer disrupts vehicle stability and occurs with what 3 driver inputs - CORRECT
ANSWERS 1. acceleration - referred to as "acceleration squat"
2. braking - referred to as "brake dive"
3. steering - referred to as a "roll"
what are the limits of adhesion - CORRECT ANSWERS 1. acceleration - tires lose traction and
spin
2. braking - tires lose traction and slide
3. cornering - tires lose traction and sideslip
several factors determine the limit of adhesion: on test - CORRECT ANSWERS 1. weight
placed on the tires
2. tire design
3. condition and type of road surface
4. the vehicle's speed (braking or accelerating)
5. the amount of turning force (slip angles)
