VADETS Module 4 Review Part 1
UPDATED ACTUAL Questions and
CORRECT Answers
Gravity - CORRECT ANSWER - ___________ is the natural force that constantly pulls
all things to the Earth and affects an object's weight.
center of gravity - CORRECT ANSWER - _______________ is a point where the mass of
a vehicle is concentrated and balanced.
Friction - CORRECT ANSWER - _____________ is the resistance that one surface or
object encounters when moving over another. It is needed for traction between the tires and the
road.
unstable - CORRECT ANSWER - The higher the center of gravity, the more
___________ the vehicle becomes.
stable - CORRECT ANSWER - The lower the center of gravity, the more _________ the
vehicle, and the less likely it is to roll.
Traction - CORRECT ANSWER - _____________ is the grip of a tire on a road. Whether
driving a small go-kart or a heavy truck, traction is necessary to move forward.
Inertia - CORRECT ANSWER - _____________ is when objects in motion tend to stay in
motion with the same speed and the same direction unless acted upon by an unbalanced force.
Potential energy - CORRECT ANSWER - the energy an object has based on its position
rather than its motion. An example is a book on a table that could possibly fall to the floor.
kinetic energy - CORRECT ANSWER - is the energy an object possesses due to its
motion (velocity [speed] and its mass [weight]).
, Momentum - CORRECT ANSWER - refers to the quantity of motion an object has. The
more mass and more velocity an object has, the more it has of this
Truck - CORRECT ANSWER - A car and A truck are traveling at 50 mph. Which vehicle
has more momentum?
Time of impact - CORRECT ANSWER - the duration of the timespan over which the
force of contact was applied (e.g., how suddenly someone braked, how fast a car was going upon
side impact, etc.).
Force of impact - CORRECT ANSWER - is the force between a vehicle and an opposing
force (e.g., how hard the brakes are applied, how heavy the vehicle that t-boned another vehicle
was, how sturdy the fence a vehicle ran into was, etc.
Impulse - CORRECT ANSWER - is a change in momentum
centripetal force - CORRECT ANSWER - pulls objects towards the center
Centrifugal forces - CORRECT ANSWER - pushes an object away from the center
True - CORRECT ANSWER - A heavier moving object will have more kinetic energy
than a lighter object moving at the same speed. (True or False)
Vehicle balance - CORRECT ANSWER - _______________ is compromised by the
constantly changing weight on the tire patches.
balanced - CORRECT ANSWER - When a vehicle is___________, the weight is over all
4 tires equally.
