| Question | Answer |
|---|---|
| force | a push or pull exerted on an object in order to change the motion of the object;force has size and direction |
| static friction | the force that resits the start of sliding motion between two surfaces that are in contact and at rest |
| kinetic friction | the energy of an object that is due to the object's motion |
| drag | a force parrell to the velocity of the flow; it opposes the directionof an aircraft and, in combination with thrust, determines the speed of the aircraft |
| feild | any region in which a physical force has an effect |
| net force | the combination of all of the forces acting on an object |
| inertia | the tendency of an object to resist a change in motion unless an outside force acts on an object |
| gravity | a force of attraction between objects that is due to their masses |
| free fall | the motion of a body when only the force of gravity is acting on the body |
| orbit | the path that a body follows as it travels around another body in space |
| electric charge | a fundamental property that leads to the electromagnetic interactions among particles that make up matter. |
| static electricity | electrical charge at rest; generally produced by friction on induction |
| electrical conductor | a material in which charges can move freely |
| electrical insulator | a material in which charges cannot move freely |
| semiconductor | an element or compound that conducts electric current better than an insulator does but not as well as a conductor does |
