    True
  • Unbalanced forces can also make objects change direction. True or false?
    True
  • stationary means it is moving. True or false?
    false
  • It means it is bend in the path taken by a moving object.
    change direction
  • It means the turning effect of a force, calculated as force x distance from a pivot.
    moment

    ASTEROID BELT
  • Primary colours can be made by mixing any other colours of light. true or false?
    false
  • It is an item that is used to hold other things, such as a beaker that contains water.
    container
  • pivot is the point about which a lever cannot turn and from which distance of a force is measured when calculating a moment. True or false?
    false
  • The Earth exerts a strong force of gravity on passing objects such as asteroids, True or false?
    true
  • The car is moving when it has unbalance forces. True or false?
    false
  • An asteroid impacts the Earth every 10 years. True or false?
    False - every 130,000 years
  • It is an interaction which, if unbalanced, will change the shape or change the movement of an object.
    force
  • The closest known galaxy to the milky way is called the Canis Major Dwarf Galaxy. True or false?
    true
  • it means a force or moments are unbalanced if their effects add together or are opposite but do not completely cancel out.
    unbalanced
  • Ceres looks like a small planet round with a diameter of 975 km and is covered with CRATERS. It has a core, mantle & crust like some planets. True or false?
    true
  • constant means the value is not the same for every input value. True or false?
    false
  • This milky band/milky way is not part of the GALAXY where we live in. True or false?
    false - it is part of our galaxy
  • graph is the way of expressing the relationship between two quantities, out of which one alters as an after-effect from the other. True or false?
    true
  • The different colours you see on a mobile phone, computer or television are all produced from combinations of the three primary colours. true or false?
    true
  • And as the particles in a liquid are moving randomly in all directions, then the pressure in the liquid is equal in all directions. True or false?
    True
  • It is the distance from the bottom of something to the top.
    depth
  • When you look at a NON-LUMINOUS object, you see the light that is reflected from the object. true or false?
    true
  • it means the speed is decrease.
    slow down
  • Sea level is the position of the surface of the ocean, usually taken mid-way between high tide and low tide. True or false?
    True
  • It is a rigid length of material that can turn about a pivot.
    lever
  • More force - more pressure. More area - less pressure. True or false?
    True
  • Violet light is refracted through the largest angle and red light is refracted through the smallest angle. true or false?
    true
  • It means to work out a value using a mathematical method or equation.
    calculate
  • It is the path taken by a moving object, or the line along which a force acts.
    direction
  • It means to hit into something.
    collide
  • The Earth’s atmosphere, which we call air, is made from gases. True or false?
    True
  • Sharp means having an edge or a point that can cut or push into another object. True or false?
    True
  • It means acting against something.
    opposite
  • safety precautions is action taken to reduce the risk of accident or injury; they are specific to the experiment and more than just basic laboratory rules. True or false?
    True
  • This is force that is equal and opposite, so their effects cancel out.
    balanced

    True
  • What is the name of the largest ASTEROID?
    Ceres
  • These are objects made from rock that orbit the Sun.
    ASTEROIDS

    true
  • This means CHANGED IN SOME WAY FROM THE ORIGINAL.
    DISTORTED
  • Altitude is height above sea level. True or false?
    True
  • Unbalanced forces not only make something move, but also slow an object down. True or false?
    True
