Forces can change the motion and speed of an object.
Forces can change the direction of an object.
Forces can change the shape of an object. This is called deformation.]]> 2020-03-18 11:40:14 UTC https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464294646 WHAT CAN FORCES DO? lizellexs https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464358922
  • Watch what happens to the objects in this clip.
  • Think about what causes that in each case.

    STUDY ALL DEFINITIONS VERBATIM!!

    • The unit in which we measure force is newtons (N). 
    • The unit of force was named after sir Isaac Newton.
    • He is recognized as one of the most influential scientists of all times.

  • Look at the pictures in the table, describing an action in each case. 
  • Decide if the force being exerted is a push or a pull and describe the effect of the force.

    See diagrams on page 6 of your notes for examples.

    Think about the types of forces you are exerting on objects in each scenario.
    Finish this activity, then draw some conclusions about force pairs.]]>     2020-03-18 13:29:13 UTC https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464437443     EXPLAIN HOW THIS IS AN EXAMPLE OF NEWTON'S 3RD LAW. lizellexs https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464444094 2020-03-18 13:33:49 UTC https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464444094 DO EXERCISE 2 ON PAGE 9 lizellexs https://padlet.com/lizellexs/cftjq9lb5jkt/wish/464445691 In each given scenario in the exercise, label the action force and the reaction force.
