  1. Net Force
  2. Motion
  3. Point of Reference
  4. Machine
  5. Speed
  1. a movement of objects, people, or animals in many different directions
  2. b When a force acts on an object and causes it to move (may be in the same direction or in opposite directions).
  3. c the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
  4. d a tool or device that makes work easier by changing the direction or the amount of force needed to move an object; DOES NOT make less work.
  5. e the relationship between the person and the moving object

5 Multiple choice questions

  1. When all the forces act on an object that are balanced and the object doesn't move; no net force.
  2. When 1 object exerts more force on another object and movement occurs. Forces may be in the same direction or opposite directions, but there is movement. There is a Net Force.
  3. When the 1st object puts a force on a 2nd object, the 2nd object will put a force back on the 1st object as well. Exam: using a hammer to pound a nail, the hammer is creating a force on the nail and the nail is creating a force back on the hammer.
  4. will demonstrate in class
  5. the rate when velocity changes over time

5 True/False questions

  1. Distancea tool or device that makes work easier by changing the direction or the amount of force needed to move an object; DOES NOT make less work.

          

  2. Newton's 2nd Law of MotionWhen the 1st object puts a force on a 2nd object, the 2nd object will put a force back on the 1st object as well. Exam: using a hammer to pound a nail, the hammer is creating a force on the nail and the nail is creating a force back on the hammer.

          

  3. Complex Machinea machine that consists of a few parts.

          

  4. NewtonsForce is measured in units called Newtons (not the cookie)

          

  5. Balanced ForcesWhen 1 object exerts more force on another object and movement occurs. Forces may be in the same direction or opposite directions, but there is movement. There is a Net Force.
