P6 Science Chapter 3: Forces @ 6:15 PM

P6 Science Chapter 3: Forces

Forces can:
  • Change shape
  • Change direction
  • Make sth move
  • make sth stop

Types of forces:

  • Gravitation force(imagine playing football w/o gravity. You're gonna wait an eternity before it comes down)
  • Elastic Spring Force
  • Frictional Force - ALWAYS OPPOSES MOTION.

~ Ways to reduce Friction:

1) Use lubricant like water/oil

2) Use ball bearings

3) Use a smoother surface

  • Magnetic force - attract/repel *Refer to P3 Science chapter 13
