  • If we stop a car, we say it is at:
    rest
  • The magnets have two of these, and the Earth does too.
    poles
  • Mention two things that can happen when we apply a force to an object:
    it may move, it may be deformed, it may be pressured
  • It is the distance covered in a certain time and in a particular direction:
    velocity
  • It is the distance covered in a certain distance (meadured in km) and at a certain time (measured in hours))
    speed
  • These are forces of nature:
    gravity and magnetic force
  • It’s the area around a magnet that attracts or pushes away something magnetic.
    Magnetic Field
  • Like a magnet, the Earth has two poles, what are their names:

    north, south, east, west
  • A force in which two things push each other away.
    Repel
  • If there are cars in ahighways, we say they may have a constant:
    velocity
  • What is acceleration?
    It's when we gradually increase the velocity.
  • It’s a force in which two things are pulled toward each other.
    Attract
  • It’s an object surrounded by a magnetic field:
    magnet
  • It’s the attraction and repulsion between two magnets.

  • What happens when you play soccer and you kick a ball?
    I transfer the energy from my foot to the ball, and the ball moves.
  • It is a pull or a push.
    A force.

    Resistance
  • A small gadget with a magnetic needle and four points labeled is called a:
