Science B05: Opposing Forces


Award-winning video and lesson investigations for young children on the topic of opposing forces

Product Description

Video and lesson investigations on the topic of opposing forces. Key concepts include:

  • Pushes and pulls make things move.
  • When two opposing pushes (or pulls) on an object are equal, movement stops. When something is still, all the pushes and pulls are balanced.
  • When forces are equal and opposite, no motion takes place.
  • In other words, if the ‘effort’ force is equal to the ‘resistance force’ there will be no motion.
  • If the opposing forces are pushing against or pulling against something with equal strength, the object will not move because the two forces are balancing each other.
  • If the forces acting on an object are unbalanced, it will move.
  • All movement depends upon forces being unequally balanced.
