★ Drivers Ed Module 3 Test Answers - Natural Forces Affecting The Driver

For safety concerning a curve, you should:
A.) shift to a higher gear
B.) accelerate while driving up the curve
C.) decelerate before the curve
D.) adjust your speed to the current road conditions

Get the Correct ANSWER

Decelerate before the curve
EXPLANATION: Following are rules for safely cornering a curve given the effects of centrifugal and centripetal forces: decelerate before the curve; brake gently and gradually if needed while turning; downshift if your car has manual transmission.


Inertia keeps your vehicle moving until a force slows it down, like __________.
A.) another vehicle
B.) strong winds
C.) applying the brake
D.) both A and C

Get the Correct ANSWER

both A and C ( applying the brake; another vehicle)
EXPLANATION: Inertia keeps your vehicle moving until another force slows it down or stops it. This force can be your own action of applying the brake, conditions of the road, an object on the road like fallen tree or—if the driver isn't paying enough attention—another vehicle.

Your vehicle's _____ affects its inertia.
A.) length
B.) height
C.) weight
D.) shape

Get the Correct ANSWER

weight


_________ is affected by your brakes, tires, the road surface, and speed.
A.) Friction
B.) Inertia
C.) Gravity
D.) Kinetic Energy

Get the Correct ANSWER

Friction
EXPLANATION: Friction is critically affected by your brakes, tires, the road surface, and speed. The brakes on your car have to be strong enough to lock the wheels into a skid. Your tires must have enough tread to create good traction, which is the gripping power of the tire as it moves on the roadway. The resistance of movement between two surfaces in contact. Friction occurs between your tires and the road, in your brakes when applied, and in many parts of your car.


When driving downhill, your vehicle will accelerate and start moving fast, due to _______________.
A.) wet pavement
B.) gravity
C.) the amount of pressure you put on the accelerator pedal
D.) kinetic energy

Get the Correct ANSWER

gravity


The force of ________ is the force at which the earth attracts another object towards itself.
A.) friction
B.) inertia
C.) gravity
D.) momentum

Get the Correct ANSWER

gravity
EXPLANATION: The force of gravity is the force at which the earth attracts another object towards itself. All objects experience the force of gravity which is directed towards the center of the earth. The force of gravity on an object is always equal to the weight of that object


Force of impact is the force ________________.
A.) of velocity
B.) generated when objects meet
C.) of acceleration
D.) of momentum

Get the Correct ANSWER

Generated when objects meet
EXPLANATION: The force of impact is the force generated when objects meet. It is a well-known fact that the faster you drive, the greater the impact or striking power of your vehicle.



Florida FLVS Drivers Ed Module 3 Test Answers - Natural Forces Affecting The Driver

Being aware of natural forces will _____________.
A.) require you to think
B.) make you paranoid while driving
C.) prepare you for emergency situations and help you avoid collisions
D.) let you have full control of the vehicle

Get the Correct ANSWER

prepare you for emergency situations and help you avoid collisions


Centrifugal force increases with _______________.
A.) traction
B.) deceleration
C.) acceleration
D.) all of the above

Get the Correct ANSWER

acceleration
EXPLANATION: Centrifugal force is the force that pulls out from the center of a body in circular motion. Centrifugal force is the opposite of centripetal force. Centrifugal force increases with acceleration.


What is the definition of "potential energy"?
A.) An object that stays at rest
B.) The energy that a piece of matter has because of its position or because of the arrangement of parts
C.) Energy that is developed by an object while it's in motion
D.) A force at which the earth attracts another object towards itself

Get the Correct ANSWER

The energy that a piece of matter has because of its position or because of the arrangement of parts
EXPLANATION: The definition of the potential energy is "the energy that a piece of matter has because of its position or because of the arrangement of parts." In other words, it is an energy that an object possesses because it has the potential to be converted into other forms of energy.


A way to prevent injuries in a collision is to ________________.
A.) take steady breaths
B.) grab onto someone else in the car
C.) wear your seat belt
D.) duck down

Get the Correct ANSWER

wear your seat belt
EXPLANATION: Imagine a car driving at 60 mph brakes hard and stops suddenly. Even though the car has stopped, the driver and passengers will continue to move forward at 60 mph until acted on by an external force. If the driver and passengers have prepared, the seat belt will be the force that stops them—if not, it will be the dashboard, windshield, or an object outside the car.


TRUE OR FALSE: When two vehicles moving at the same rate of speed are involved in a collision, the vehicle that weighs less will take the greater impact.
A.) True
B.) False

Get the Correct ANSWER

True


TRUE OR FALSE: Without the seat belt restraint system, unbelted persons will hit the car interior or anything that comes in their way with a tremendous amount of force.
A.) True
B.) False

Get the Correct ANSWER

True
