  1. 1. When an object is moving - what effect will a balanced force have on the object? A. The object will start moving faster.B. The object will slow down.C. The object will speed up to a steady speedD. The object will not move.

  2. 2. What force acts upward and is an opposite force to gravity?A. WeightB. ReactionC. Gravity SupportD. Air Resistance

  3. 3. Describe the motion of a stationary object if an unbalanced force acts on it.A. The object will remain stationary.B. The object will decelerate.C. The object will begin moving (accelerate)D. The object will accelerate and decelerate.

  4. Newton's first law of motion states that an object will keep a constant velocity unless acted upon by an unbalanced force. To test this statement, Martin rolled a ball on a long, level street. The ball did not bump into any object, but it eventually came to a stop. How is this possible? A. Every moving object must come to a stop because energy cannot be destroyed. B. The unbalanced force that caused the ball to stop was friction. C. Newton's first law of motion only holds true in space, not on Earth. D. Martin did not roll the ball hard enough, which caused the ball to eventually stop rolling.

  5. Force is measured in which units?A. Degrees B. NewtonsC. Meter D. Grams

  6. Speeding up, slowing down, and changing direction are all examples of _______.A. fluid frictionB. velocityC. accelerationD. Speed

  7. According to Newton’s second law, acceleration depends on the mass of the object and the __________.A. size of the force.B. direction of the force.C. distance traveled.D. speed of the object.

  8. 8. Why does a flat sheet of paper fall more slowly than a sheet of paper crumpled into a ball?A. the crumpled sheet has less mass than the flat sheet.B. The flat sheet has no net force.C. The flat sheet has a larger surface area and so air resistance is greater.D. The crumpled sheet has greater potential energy.

  9. The force of friction exists between objects that ______.A. are movingB. have different massesC. are in contactD. have rough surfaces

  10. 10. If balanced forces act on an object, the object ______.A. stays in the same position.B. changes velocity.C. changes direction.D. stops moving.
