Term
|
Definition
The study of the description of motion, including considerations of space and time. What the motion looks like, includes how far the motion travels (space), and how fast the motion travels (time). |
|
|
Term
|
Definition
The study of action of forces (create movement). Why motions happen. |
|
|
Term
|
Definition
Branch of mechanics dealing with systems in a constant state of motion. Either no motion (rest) or motion of constant velocity (no change in direction or speed). |
|
|
Term
|
Definition
Branch of mechanics dealing with systems subject to acceleration. Change in motion (speed up/slow down) or direction (turning). |

Exclusively with amount (magnitude). EX: Time, temperature. |
|
|
Term
|
Definition
Describe with amount (magnitude) and direction (velocity). EX: Weight, force. |
|
|
Term
|
Definition
Tendancy of a body to resist a change in its state of motion (does not want to change its motion, whatever the motion may be). The more mass, the more inertia. |

Definition
Vector. Push or pull. The product of mass and acceleration. |
|
|
Term
|
Definition
Point around which a body's weight is equally balanced, no matter how the body is positioned. |
