1. For every action, there is an equal but opposite reaction. This is ........ Newton's First law of motion Newton's Second law of motion Newton's Third law of motion 2. An object in motion will remain in motion andan object at rest will remain at rest, unless acted upon by a force. This is .......... Newton's second law of motion Newton's first law of motion Newton's third law of motion 3. Net force is equal to mass times acceleration. (E = m a) Acceleration depends on mass of the object and the forceapplied. This is ......... Newton's first law of motion Newton's second law of motion Newton's third law of motion 4. A push or pull on an object is: Friction Gravity Mass Force 5. The distance an object can travel, and the amount of time it took to go that distance is referred to as...... Acceleration Speed Velocity 6. A balanced force is: Forces of equal strength acting in the same direction to the right. Forces of equal strength acting in the same direction to the left. Forces of equal strength acting in opposite directions. 7. An unbalanced force is: When the force acting on an object changes the position, direction, or speed of the object's motion. When the force acting on an object changes does not change the position, direction, or speed of the object's motion. No change in motion. It's a tie. Forces of equal strength. 8. How will this object move? It won't move It will move to the right with 20 N of force. It will move to the left It will move to the right with 80 N of force. 9. What is the net force? 30 N left 5 N left 25 N right 55 N right 10. Calculate the net force. 60 N left 0 N balanced 100 N right 60 N right 11. Calculate the net force. 0 N balanced 40 N left 75 N right 40 N right 12. The tendency of an object at rest to stay at rest unless acted upon by a force is called: inertia gravity lubricant motion 13. Forces that have a net force of zero (the object is still). balanced force unbalanced force 14. All the combined forces exerted on an object.... Contact Force Unbalanced Force Balanced Force Net Force 15. What will cause an object to move? Unbalanced forces Applied forces Balanced forces 16. Which of the following is not a distance force? A C B D 17. Which of the following is not a contact force? C A B D 18. What is the net force and direction of the bird? 9 N up 9 N down 31 N down 41 N up 19. What is the unit of force? Pascal Kilogram Newton Meter 20. Why does a book on a table not move? No forces are acting on the book Gravity is the only force acting on the book. Forces of the table pushing up and gravity pulling down are balanced |
