Resource summary

Question 1

Question
What is the equation for speed?
Answer
  • time / distance
  • change in speed / time taken
  • time x distance
  • distance / time

Question 2

Question
A steeper slope means a slower speed
Answer
  • True
  • False

Question 3

Question
What is acceleration?
Answer
  • speed of an object in a certain direction
  • the change in speed per second
  • the time taken for a change in speed
  • frictional force that acts on a moving object

Question 4

Question
What are forces measured in?
Answer
  • Newtons (N)
  • Kilograms (kg)
  • Watts (W)
  • Joules (J)

Question 5

Question
How can thinking distance be increased?
Answer
  • icy/wet road conditions
  • tiredness
  • worn brakes or tyres
  • mass of vehicle

Question 6

Question
What is the equation for stopping distance?
Answer
  • thinking distance x braking distance
  • thinking distance + braking distance
  • braking distance / stopping distance x100
  • stopping distance - thinking distance

Question 7

Question
Work is done whenever a force moves an object
Answer
  • True
  • False

Question 8

Question
What is power measured in?
Answer
  • Joules ( J )
  • Watts (W)
  • Newtons ( N )
  • Kilograms ( kg )

Question 9

Question
What is kinetic energy?
Answer
  • energy when you stand still
  • energy an object has because of its movement
  • increased speed of an object
  • a force of attraction between masses

Question 10

Question
Cars with a greater kinetic energy will have a lower braking distance
Answer
  • True
  • False

Question 11

Question
What do seatbelts do?
Answer
  • cushion the impact for the driver and passengers
  • absorb energy and break to avoid the driver being impaled during an accident
  • prevent people in the car from being propelled forwards
  • be a part of the car designed to crumple up during a collision

Question 12

Question
What do air bags do?
Answer
  • cushion the impact for the driver and passengers
  • absorb energy and break to avoid the driver being impaled during an accident
  • prevent people in the car from being propelled forwards
  • be the part of the car designed to crumple up during a collision

Question 13

Question
What do crumple zones do?
Answer
  • cushion the impact for the drivers and passengers
  • absorb energy and break to avoid the driver being impaled during an accident
  • prevent people in the car from being propelled forwards
  • be the part of the car designed to crumple up during a collision

Question 14

Question
What is the equation for momentum?
Answer
  • mass x acceleration
  • mass x velocity
  • force / time taken
  • mass / acceleration

Question 15

Question
At higher speeds, falling objects experience more drag
Answer
  • True
  • False

Question 16

Question
When a skydiver jumps out of an aeroplane, what does he initially do?
Answer
  • deaccelerate due to air resistance
  • accelerate due to the force of gravity
  • accelerate due to air resistance
