Answer

braking distance

Question 12

What is the name given to the distance a vehicle travels during driver’s reaction time?

Accepted Answer

thinking distance

Answer

stopping distance

Answer

braking distance

Question 13

What is the name given to the distance a vehicle travels once brakes have been applied?

Accepted Answer

braking distance

Answer

thinking distance

Answer

stopping distance

Question 14

What is the relationship between stopping distance, thinking distance, and braking distance?

Accepted Answer

$\begin{matrix}
	ext {stopping} \
	ext {distance}
\end{matrix}= 	ext {thinking distance + braking distance}$

Answer

$\begin{matrix}
	ext {stopping} \
	ext {distance}
\end{matrix}= 	ext {thinking distance / braking distance}$

Answer

$\begin{matrix}
	ext {thinking} \
	ext {distance}
\end{matrix}= 	ext {stopping distance + braking distance}$

Answer

$\begin{matrix}
	ext {braking} \
	ext {distance}
\end{matrix}= 	ext {thinking distance + stopping distance}$

Question 15

Which of these is NOT a factor that can affect the braking distance of a vehicle?

Accepted Answer

Answer

condition of tyres and brakes

Answer

speed of the vehicle

Answer

road conditions

Question 16

Which of these points does NOT describe what may happen if the braking force of a vehicle is very large?

Accepted Answer

the car may stop too slowly leading to accidents

Answer

the car may skid

Answer

the driver may lose control of the vehicle

Answer

brakes may overheat

Question 17

What is the law of conservation of momentum?

Accepted Answer

in a closed system, the total momentum before an event is equal to the total momentum after it

Answer

in a closed system, the total momentum before an event is less than the total momentum after it

Answer

in an open system, the total momentum before an event is equal to the total momentum after it

Answer

in a closed system, the total momentum before an event is greater than the total momentum after it

Question 18

What is the formula that shows the relationship of force acting on an object and the rate of change of its momentum?

Accepted Answer

$\begin{matrix} 	ext {force acting} \ 	ext {on an object} \end{matrix}= 	ext {change of momentum} / 	ext {time taken}$

Answer

$\begin{matrix} 	ext {force acting} \ 	ext {on an object} \end{matrix}= 	ext {change of momentum} $

Answer

$\begin{matrix} 	ext {force acting} \ 	ext {on an object} \end{matrix}= 	ext {change of momentum}$ x $	ext {time taken}$

Answer

$\begin{matrix} 	ext {change of} \ 	ext {momentum} \end{matrix}= 	ext {force acting on an object} / 	ext {time taken}$
