Questions and Answers

What is the definition of a force?

  • A resistance to changes in motion
  • An effect that causes motion
  • A push or a pull (correct)
  • A movement that changes the position of an object

    • What happens when two forces acting on an object are balanced?

  • The object accelerates in the direction of the greater force
  • The object changes direction
  • The object remains at rest or in constant motion (correct)
  • The object experiences increased resistance

    • What is gravity?

  • A force that pushes objects away from each other
  • An invisible force that resists motion
  • An invisible force that pulls objects toward the Earth (correct)

    Study Notes

    Forces

    • A force is a push or a pull that can change an object’s motion
    • A push is a force that moves an object away from you.
    • A pull is a force that moves an object toward you.
    • Balanced forces are equal forces that push or pull in opposite directions, resulting in no movement of the object.
    • Unbalanced forces are unequal forces that push or pull in opposite directions, causing the object to move.
    • Friction is a force that opposes motion, making it harder for an object to move.
    • Gravity is a force that pulls everything towards the center of the Earth.

    Motion

    • Motion is the change in an object's position.
    • A pattern of motion exists when a moving object repeats the same movement over and over again.

    Magnets

    • All magnets have a North pole and a South pole.
    • Magnetic fields are invisible areas around magnets where they can exert forces, affecting other objects.
    • Magnetism can be used to solve various problems:
      • Holding objects to a refrigerator
      • Picking up small objects from the floor
      • Using a compass to determine North
    • Iron is an example of a material that is magnetic.
    • Magnets do not need to touch an object to affect it.
    • Objects with the same magnetic charge repel each other.
    • The largest magnet on Earth is the planet itself.

    Forces

    • A force is a push or a pull.
    • A push moves an object away from you.
    • A pull moves an object towards you.
    • Balanced forces are two equal forces pushing or pulling in opposite directions, resulting in no movement.
    • Unbalanced forces are two forces pushing or pulling in opposite directions with one force being greater, resulting in movement.
    • Friction is a force resisting the motion of an object.
    • Gravity is a force pulling objects towards the Earth.

    Motion

    • Motion is a change in position of an object.
    • A pattern of motion is created when a moving object repeats the same pattern.

    Magnets

    • All magnets have a north and a south pole.
    • Magnets attract and repel objects.
    • A magnetic field is the invisible space where a magnet can exert its force.
    • Magnets can be used to hold objects, pick up small objects, and determine north with a compass.
    • Iron is a magnetic material.
    • Magnets don't need to touch an object to apply a force.
    • Objects with the same charge repel each other.
    • Earth is the biggest magnet on the planet.
