INERTIA |
THE TENDENCY OF AN OBJECT TO RESIST A CHANGE IN MOTION- ex. ball rolling or rock on ground |
|
|
MASS |
THE AMOUNT OF MATTER THAT MAKES UP AN OBJECT ex. a tennis ball has a mass of 45g |
|
|
NEWTON'S 1ST LAW (The Law of Inertia) |
AN OBJECT WILL STAY IN MOTION OR WILL STAY AT REST UNLESS ACTED UPON BY UNBALANCED FORCE- friction stops ball or kicking moves rock. |
|
|
NEWTON'S 2ND LAW (The law of force and acceleration) 1 2 |
F = ma Force = mass times (X) acceleration The acceleration of an object is dependent on the amount of force applied and the mass of the object.ex. small mass= large acceleration large mass = small acceleration |
|
|
NEWTON'S 3RD LAW (The law of action and reaction) 1 2 3 |
FOR EVERY ACTION THERE IS AN EQUAL BUT OPPOSITE REACTION |
|
|
NEWTON |
N = A MEASUREMENT OF FORCE |
|
|
UNBALANCED FORCE |
THE NET FORCE OF AN OBJECT DOES NOT EQUAL ZERO WHICH RESULTS IN A CHANGE IN THE MOTION (IT MOVES) |
|
|
FORCE |
A PUSH OR PULL |
|
|
ACCELERATION |
THE RATE AT WHICH AN OBJECT'S SPEED AND/OR DIRECTIONS CHANGES OVER TIME |
|
|
NET FORCE |
TOTAL FORCES ACTING ON THE OBJECT |
|
|
BALANCED FORCE |
WHEN THE NET FORCES ARE EQUAL= NOT MOVING |
