Q.1
What can affect a vehicle's braking distance?
  • Worn brakes
  • Adverse weather
  • Worn tires
  • All of the above
Q.2
Which of the following statements is true?
  • The greater the speed of a vehicle, the greater the braking force needed to stop it within a certain distance
  • The smaller the speed of a vehicle, the greater the braking force needed to stop it within a certain distance
  • The greater the speed of a vehicle, the less braking force is needed to stop it within a certain distance
  • The greater the mass of a vehicle, the less braking force is needed to stop it within a certain distance
Q.3
What is stopping distance?
  • Braking distance
  • Reaction time
  • Braking distance and reaction distance
  • Reaction distance
Q.4
What is the greatest resistive force a car experiences when no braking forces are applied?
  • Air resistance
  • Passenger weight
  • Stones
  • Rain
Q.5
What is braking distance?
  • The distance traveled in 10 seconds when a car is accelerating
  • The distance traveled while the brakes are applied
  • The distance required to accelerate to 100mph
  • The energy required to stop in a given distance
Q.6
Which statement is true?
  • When the brakes are applied, work done by friction between the brake and wheel increases the kinetic energy of the vehicle and decreases the temperature of the brakes
  • When the brakes are applied, work done by friction between the brake and wheel reduces the kinetic energy of the vehicle and increases the temperature of the brakes
  • When the brakes are released, work done by friction between the brake and wheel reduces the kinetic energy of the vehicle and increases the temperature of the brakes
  • When the brakes are applied, work done by friction between the brake and wheel reduces the kinetic energy of the vehicle and decreases the temperature of the brakes
Q.7
If a driver's reaction time is 0.2 s and the braking time when their car is traveling at 10 m/s is 10 s, how far does the car travel before it comes to rest?
  • 100m
  • 101m
  • 102m
  • 103m
Q.8
A car stops in 20 m when traveling at 30 kilometers per hour. If the car is traveling at 40 kilometers per hour, how far does the car take to stop?
  • 20m
  • 26m
  • 27m
  • 30m
Q.9
If a car is traveling at a steady speed, what can be said of the driving and resistive forces acting on the car?
  • In equilibrium
  • Driving forces are twice as large as the resistive forces
  • Resistive forces are twice as large as the driving forces
  • There are no resistive forces acting on the car at a steady speed
Q.10
