FORCE
2
A FORCE IS A PUSH OR A PULL. IF FORCES ARE POWERFUL ENOUGH, THEY MAY RESULT IN MOTION. What is a force?
3
IF THE NET FORCE ACTING ON AN OBJECT IS ZERO, THE OBJECT REMAINS AT REST, OR IF IT IS ALREADY MOVING, IT REMAINS MOVING. Newton’s first law of motion
4
STATIC FRICTION - OCCURS WHEN AN OBJECT IS AT REST SLIDING FRICTION - WHEN AN OBJECT IS SLIDING ACROSS A SURFACE ROLLING FRICTION - WHEN AN OBJECT IS ROLLING ACROSS A SURFACE. Three Types of Friction
5
THE SECOND LAW STATES THAT THE FORCE ON AN OBJECT IS EQUAL TO THE OBJECT'S MASS TIMES IT ACCELERATION: F = MA Newton’s second law
6
NEWTON'S 3RD LAW STATES THAT FORCES ALWAYS ACT IN EQUAL AND OPPOSITE PAIRS. WHEN ONE OBJECT EXERTS A FORCE ON A SECOND OBJECT, THE SECOND OBJECT ALSO EXERTS A FORCE ON THE FIRST. Newton’s third law of motion
7
1ST LAW: INERTIA LARGE BOULDER, HARD TO START MOVING, HARD TO STOP MOVING 2ND LAW: FORCE APPLIED TO AN OBJECTWILL ACCELERATE THE OBJECT --SMALL OBJECT ACCELERATES RAPIDLY,LARGE OBJECT ACCELERATES SLOWLY. 3RD LAW: EQUAL AND OPPOSITE REACTIONS ROCKET, SKATEBOARD Examples of Newton’s laws
8
MASS IS THE TOTAL AMOUNT OF MATTER IN AN OBJECT. WEIGHT IS THE MEASURE OF THE ATTRACTION OF GRAVITY TO AN OBJECT. What is the difference between mass and weight?
