  • 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’s an object surrounded by a magnetic field:
    magnet
  • What is acceleration?
    It's when we gradually increase the velocity.
  • It happens when a force prevents or slows down something from moving:
