  • What is the force that stops things
    Friction (the force that tries to slow tings tow when two things rub against each other​)​
  •  15
  • What is force
    A push or a pull applied to an object.
  •  15
  • What is a contact force
    A interactions between object that touch
  •  15
  • What is net force
    the sum of all the forces acting on an object
  •  20
  • What is the effects of forces on motion​
    Change the shape of an object.​​ Move/speed-up an object.​​ Stop/slow down a moving object.​​ Change the direction of a moving object.​ ​
  •  25
  • What is a unbalanced forces
    object’s motion will change (speed up/slow down and change direction​)
  •  20
  • How is a rough surface effect the friction
    It will be having higher friction
  •  15
  • What are the two measurements should they make?
    Masses on the materials, force of pull required.​
  •  20
  • What is gravity?
    A force that pulls objects towards each other​ (Affected by mass and distance​ The more mass an object has, the higher its gravity is​ The closer two objects

  • Harid said you will be taller in space, so he will have more mass. Do you agree with him, why.
    No, wherever are you, your mass is still the same (
  •  15
  • What is formula of finding Weight
    Mass x 10 (N/kg)
  •  15
  • What happen if the mass increase?
    The force of gravity increase.
  •  20
  • How is going to land slower (Right or Left)
    Left
  •  15
  • What is a Vacuum (science)
    Devoid of all matter = a space there where is no matter​
  •  15
  • Why is space is not a vacuum?
    It has atoms in it.
  •  15
  • Tammy guess that without matter, both the bowling ball and the feather would drop at the same time. Explain why is she correct.
    Because air resistance is a frictional force between air and an object, since air is matter, and without matter, air resistance is not gonna work.​
