Presentation Transcript

  1. FORCE – PUSH OR PULL The unit of measurement for force is the Newton (N)

  2. FORCES ACT IN PAIRS BALANCED FORCES – OCCURS WHEN THE FORCES ACTING ON AN OBJECT ARE EQUAL TO EACH OTHER AND THERE IS NO MOVEMENT.

  3. UNBALANCED FORCES – OCCURS WHEN THE FORCES ACTING ON AN OBJECT ARE NOT EQUAL TO EACH OTHER AND THERE IS MOVEMENT.

  4. FRICTION – A FORCE THAT PUSHES AGAINST MOVING OBJECTS.

  5. AIR RESISTANCE – A FORM OF FRICTION THAT EXISTS BETWEEN OBJECTS MOVING THROUGH THE ATMOSPHERE.

  6. GRAVITY – A PULLING FORCE OF ATTRACTION THAT EXIST BETWEEN ANY TWO OBJECTS WITH MASS.

  7. GRAVITY PULLS ALL OBJECTS DOWN AT THE SAME RATE. WITHOUT AIR RESISTANCE WITH AIR RESISTANCE (VACUUM)

  8. WORK – THE ACTION THAT RESULTS WHEN A FORCE CAUSES AN OBJECT TO MOVE IN THE DIRECTION OF THE FORCE. Work = Force x Distance (W=FxD) Joule (J) is the unit of measurement for work

  9. HOW MUCH WORK HAS BEEN DONE IN EACH SITUATION BELOW? W=FxD Ms. Johnson used a force of 10 Newtons to push a box 5 meters across the floor. How much work did she do? ______Joules Mrs. Wit Mal used a force of 100 Newtons to pull a desk 2 meters across the floor. How much work did she do? ______Joules Mr. Moore used a force of 1,000 Newtons to pull a car 0 meters down the street. How much work did he do? ______Joules

  10. HOW MUCH WORK HAS BEEN DONE IN EACH SITUATION BELOW? W=FxD Ms. Johnson used a force of 10 Newtons to push a box 5 meters across the floor. How much work did she do? 50 Joules Mrs. Wit Mal used a force of 100 Newtons to pull a desk 2 meters across the floor. How much work did she do? 200 Joules Mr. Moore used a force of 1,000 Newtons to pull a car 0 meters down the street. How much work did he do? 0 Joules

  11. ENERGY – THE ABILITY TO DO WORK.
