  2. 2. What is a force? <ul><li>A force is a push or pull that causes an object to move, stop, or change direction </li></ul><ul><li>In physics a force is anything that makes an object accelerate </li></ul>
  3. 3. Force <ul><li>Forces come in pairs </li></ul><ul><li>Forces have a magnitude and a direction </li></ul>5N, north (up) Magnitude: 5N Direction: north (up)
  4. 4. Balanced and Unbalanced Forces <ul><li>Forces occur in pairs and they can be either balanced or unbalanced </li></ul>
  5. 5. Balanced Forces <ul><li>Balanced forces do not cause change in motion </li></ul><ul><li>They are equal in size and opposite in direction </li></ul>
  6. 6. Unbalanced Forces <ul><li>An unbalanced force always causes a change in motion </li></ul><ul><li>When unbalanced forces act in opposite directions you can find the net force </li></ul><ul><ul><li>Net force </li></ul></ul><ul><ul><ul><li>Magnitude </li></ul></ul></ul><ul><ul><ul><ul><li>The difference between the two forces </li></ul></ul></ul></ul><ul><ul><ul><li>Direction </li></ul></ul></ul><ul><ul><ul><ul><li>Direction of the largest force </li></ul></ul></ul></ul>
