Term
|
Definition
| Every object continues in a state of rest, or in a state of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it. |

|
Term
|
Definition
| When two values change in opposite directions, so that if one increases and the either decrease by the same amount, they are said to be inversely proportional to each other. |

Definition
| The force due to gravity on an object. |
|
|
Term
|
Definition
| The fundamental unit of mass. |
|
|
Term
|
Definition
| The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the net force, and is inversely proportional to the mass of an object. |
|
|
Term
|
Definition
| The resistive force that opposes the motion or attempt motion of an object past another with which it is in contact or through a fluid. |
|
|
Term
|
Definition
| Motion under the influence of gravitational pull only. |
|
|
Term
|
Definition
| Frictional resistance due to motion through the air. |
|
|
Term
|
Definition
| The speed at which the acceleration of a falling object terminates because air resistance balances its weight. |
|
|
Term
|
Definition
| Terminal speed with direction of motion. |
|
|
Term
|
Definition
| Mutual action between objects where each object exerts equal ad opposite force on the other. |
|
|
Term
|
Definition
| The action and reaction pair of forces that occurs in an interaction. |
|
|
Term
|
Definition
| For every action there is an opposite and equal reaction. |

| Action force and reaction force |
|
|
Term
| What's the difference of speed and velocity? |
|
Definition
| Speed is the rate of motion WITHOUT direction, velocity is the rate of motion WITH a direction. |

| What is the name of the force when a piece of rope is pulled in opposite directions? |
|
Definition
|
|
Term
| What were the two main classifications of motion in Aristotle's view of nature? |
|
Definition
|
|
Term
Did Aristotle believe that forces are necessary to keep moving objects moving, or did he believe that,
once moving, they'd move of themselves? |
|
Definition
|
|
Term
| What two main ideas of Aristotle did Galileo discredit? |
|
Definition
| Falling objects, force and movement. |
|
|
Term
| Which dominated Galileo's way of extending knowledge-philosophical discussion or experiment? |
|
Definition
|
|
Term
| What is the name of the property of objects to maintain their states of motion? |
|
Definition
|
|
Term
| Which depends on gravity-weight or mass? |
|
Definition
|
|
Term
| Where would your weight be greater-on the earth or on the moon? How about your mass? |
|
Definition
| Weight less on moon, mass the same in both places |
|
|
Term
| What are the units of measurement for weight and for mass? |
|
Definition
| Weight – lbs, or newtons. Mass - kilograms |

Term
| What two quantities are necessary to determine a vector quantity? |
|
Definition
|
|
Term
|
Definition
| Mechanical equilibrium, net force is zero |
|
|
Term
| Why is the support force on an object often called the normal force? |
|
Definition
| Because it is perpendicular to the surface. |
|
|
Term
| What is the relationship between mass and inertia? |
|
Definition
| Mass measures inertia. Greater the mass, greater the inertia. |
