  • Q1
    What is the gravitational field strength on our planet ?
    5 N/ Kg
    20N/kg
    10 N / kg
    15 N /Kg
    30s
  • Q2
    What is the units for 'weight' ?
    tonnes
    newtons
    grams
    Kilograms
    30s
  • Q3
    What is the equation for calculating weight ?
    weight = mass
    weight= mass - gravity strength
    weight= mass + gravity strength
    weight = mass x gravity strength

  • Q4
    Calculate the weight of a 45 Kg dog ( remember how strong gravity is on our planet)
    360 N
    452 N
    455 N
    450 N
    30s
  • Q5
    If the upthrust on the wings of a plane is 5000 N and the weight of the plane is 3000 N. What size is the resultant force and what is it's direction ?
    2000 N upwards
    2000 N downwards
    8000 N upwards
    2000 N downwards

  • Q6
    What two distances make up the total stopping distance ?
    braking distance + reaction time
    braking distance + thinking distance
    accelerating distance + braking time
    looking distance + driving distance
    30s
  • Q7
    What will happen if the driver of a car has been drinking ?
    Thinking distance will increase
    braking distance will decrease
    Braking distance will increase
    Thinking distance will decrease
    30s
  • Q8
    What part of stopping distance will worn tyres affect ?
    braking distance
    reaction time
    thinking distance
    braking time
    30s
  • Q9
    What is a typical reaction time of a human ?
    0.35
    0.25 seconds
    0.5
    0.1
    30s
  • Q10
    What is the equation that links force, mass and acceleration ?
    force = mass - acceleration
    Force = mass x acceleration
    acceleration = force x mass
    mass = force x acceleration
    30s
  • Q11
    What is the force needed to accelerate a mass of 6 Kg by 3 m/s2
    18 N
    1800 N
    2 N
    0.5 N
    30s
  • Q12
    Name a factor that can affect a driver's reaction time .
    type of tyres
    speed of car
    tiredness
    type of road surface
    30s
  • Q13
    How will a wet surface of a road affect the stopping distance of a car ?
    thinking distance will increase
    braking distance will decrease
    reaction time will increase
    braking distance will increase
    30s
  • Q14
    What is meant by 'balanced forces ' ?
    When opposite forces are a similar size
    Forces that are the same size and act in opposite directions
    Forces that balance objects
    Forces that are the same size
