Keywords:
  • Force (3)
  • Combined: Two or more entities adding into one single entity (1)
  • Resultant force: The combined force. (1)
  • Balanced (1)
  • Newtons (1)
  • Newtons: unit of measure of force kgm/s^2 (1)
  • Force arrows: arrows which show the direction of a force on a body (1)
  • Free body diagram: a diagram which is used to show all forces acting on a body (1)
  • Force: Pushing or pulling (1)

T Forces can be either pushes or pulls, which can be combined to form a twist. What is a force?
W Force arrows in free body diagrams are used to show the direction of forces and the size of the force by its length or label. Force arrows have a solid arrow head. What do we use force arrows for? How do we draw them?
T Forces are measured in newtons with the symbol 'N'. What do we measure forces in? What symbol can we use?
T A newton is the weight of a small apple. What is one Newton equivalent to?
W Forces can be combined to help or cancel each other. What happens if forces are combined?

Role play combining forces with Force arrow props.
T Adding forces in 1 dimension, allows to calculate whether forces are balanced or unbalanced. Forces in the a backwards direction are considered negative. The combined force is is called the 'Resultant force' and is the result of adding all the forces together. How do we calculate whether forces are balanced or unbalanced? How can we tell if a force is negative? What is the 'resultant force'?
