What Is a Force?Chapter 1 Section 2 Review 1. What is a newton?A. A moving objectB. A point of referenceC. The SI unit for forceD. A push or pull A newton isC. The SI unit for force

2. Force isA. A great deal of weightB. A push or pull exerted on an object in order to change the objects motionC. A change in position relative to a reference pointD. The speed of an object in a certain direction

A force isB. A push or pull exerted on an object in order to change the objects motion

3. What is net force?A. A blocker in volleyballB. A push or pullC. The speed of an object in a certain directionD. The combination of all forces acting on an objectNet force isD. The combination of all forces acting on an object

4. Are the forces on a kicked football balanced or unbalanced? Why?A. Balanced, since the football is movingB. Unbalanced, since the football is movingC. Balanced, since the football is stillD. Unbalanced, since the football is stillThe forces on a kicked football areB. Unbalanced, since the football is moving

5. Which of the following choices best represents force?A. A push or pull always causing motionB. A push or pull always causing accelerationC. A push or pull acting without an objectD. A push or pull acting on an objectForce is represented byD. A push or pull acting on an object

6. A boy pulls a wagon with a force of 8 N West as another boy pushes it with a force of 6 N West. What is the net force?A. 14 N EastB. 2 N WestC. 2 N EastD. 14 N West

8 N West + 6 N West =D. 14 N West7. Which of the following best determines net force when more than one force is acting on an object?A. A combination of all motions of an objectB. A combination of all motions of an object in 2 directionsC. A combination of all forces acting on an objectD. A combination of forces acting on an object in 2 directionsNet force is best determined whenC. A combination of all forces is acting on an object

8. Which of the following may happen when an object receives unbalanced forces?A. The object changes directionB. The object changes speedC. The object starts to moveD. All of the aboveWhen an object receives unbalanced forces, it moves, soD. All of the above

9. When the net forces equal 0 N, they are which of the following?A. BalancedB. UnbalancedC. A pushD. A pullWhen net forces equal 0 N, they areA. Balanced

10. What is an example of an unbalanced force causing a change in motion?A. Pulling on a drawer so it opensB. Pushing a chair across the floorC. Pedaling a bicycleD. All of the aboveD. All of the above11. Which of the following always causes a change in speed, direction, or both?A. Balanced forcesB. Unbalanced forcesC. Either balanced or unbalanced forcesD. Any combination of forcesB. Unbalanced forces12. What is an example of an object that has balanced forces acting on it? A. A car going down the streetB. A book resting on a tableC. A kid riding a bikeD. A windmill turningB. A book resting on a table

13. Which of the following causes an object to start moving?A. Balanced forcesB. Unbalanced forcesC. Either balanced or unbalanced forcesD. Any combination of forcesB. Unbalanced forces14. One Newton is the equivalent ofA. About 100 gramsB. 1 poundC. 1 appleD. 10 grams1 Newton is equal toA. About 100 grams
