  5. Physical Science: Chapter 11Section 3 Motion & Force Mini-Quiz #5 1). What is a force? 2). What are contact forces? 3). What are field forces? 4). Which fundamental forces of nature are field forces?

  6. Forces ________________________Forces • If all the forces are _______________, there is no “______” force and there is ____________________________________. ____________________________Forces • If the forces are ________________, the “_____” force causes a _____________in the __________________.

  7. Physical Science: Chapter 11Section 3 Motion & Force FRICTION _________ is a force that “_________” motion; it works in the ___________________________ of a ______force applied to an object to get it to ____________.

  8. Friction • Friction in machines _____________ their ________________, making them more expensiveto use and wearing them out faster. • Friction in machines can be reduced by using _________________, like oil.

  9. Friction • Friction is not always a ______thing. Friction is needed for ____________________________ • When needed, friction can be increased in two ways: 1. ______________________________________ 2. ______________________________________ • (example: add weight above the rear wheels to increase traction.)

  10. Two Types of Friction • ________________________ Friction The force that works between two surfaces that are ___________and at ______(____________). • _____________________ Friction The force that works between two _________ objects (or one that is ________and one that is __________________________).

  11. Physical Science: Chapter 11Section 3 Motion & Force Kinetic Friction • There are two types of ____________friction: _________Friction__________ Friction
