Newton's 2nd Law
Mr. Lang's Physics A
Term | Definition |
---|---|
Acceleration | change in velocity (speed up, slow down, or turn) equation:(Velocity/time) & (vector quantity) |
Net Force | the total of all forces acting on an object (Vector quantity) |
Directly Proportional | relationship between two variables that change by the same factor (3A = 3B.. or 1/2A = 1/2B) |
magnitude | The "SIZE" of a quantity |
Inversely Proportional | relationship between two variable change by opposite factors (3A = 1/3B or 1/4A = 4B) |
mass | amount of matter in an object (scalar quantity) |
Force | push or pull (vector quantity) |
weight | a common force that if caused by gravity (vector) |
Vector quantity | a quantity that has both magnitude and direction (direction = east, up, degrees, +/-) |
scalar quantity | a quantity that has only magnitude |
speed | simply how fast (scalar quantity) |
velocity | how fast in a specific direction (vector quantity) |
