Circular motion Flashcards
MOTION
IS THE PROCESS OF CHANGING POSITION
REFERENCE POINT
THE STARTING POINT YOU USE TO DESCRIBE THE MOTION OR THE POSITION OF AN OBJECT
DISTANCE
THE TOTAL LENGTH OF A PATH
DISPLACEMENT
THE DISTANCE BETWEEN YOUR INITIAL, OR STARTING, POSITION AND YOUR FINAL POSITION
SPEED
THE DISTANCE AN OBJECT MOVES DIVIDED BY THE TIME IT TOOK TO MOVE THAT DISTANCE
VELOCITY
THE SPEED AND DIRECTION OF AN OBJECT’S MOTION
ACCELERATION
THE MEASURE OF HOW QUICKLY THE VELOCITY OF AN OBJECT CHANGES
FORCE
A PUSH OR PULL ON AN OBJECT
CONTACT FORCE
A PUSH OR A PULL APPLIED BY ONE OBJECT TO ANOTHER OBJECT THAT IS TOUCHING IT
FRICTION
A CONTACT FORCE THAT RESISTS THE SLIDING MOTION BETWEEN TWO OBJECTS THAT ARE TOUCHING
GRAVITY
A NONCONTACT ATTRACTIVE FORCE THAT EXISTS BETWEEN ALL OBJECTS THAT HAVE MASS
BALANCED FORCES
WHEN THE NET FORCE ON AN OBJECT IS 0 N
UNBALANCED FORCES
WHEN THE NET FORCE ACTING ON AN OBJECT IS NOT 0
NONCONTACT FORCE
A FORCE THAT PUSHES OR PULLS AN OBJECT WITHOUT TOUCHING IT
INERTIA
THE TENDENCY OF AN OBJECT TO RESIST A CHANGE IN MOTION
NEWTON´S FIRST LAW OF MOTION
STATES THAT IF THE NET FORCE ACTING ON AN OBJECT IS ZERO, THE MOTION OF THE OBJECT DOES NOT CHANGE
NEWTON´S SECOND LAW OF MOTION
STATES THAT THE ACCELERATION OF AN OBJECT IS EQUAL TO THE NET FORCE EXERTED ON THE OBJECT DIVIDED BY THE OBJECT’S MASS
NEWTON´S THIRD LAW OF MOTION
STATES THAT WHEN AN OBJECT EXERTS A FORCE ON A SECOND OBJECT, THE SECOND OBJECT EXERTS A FORCE OF THE SAME SIZE, BUT IN THE OPPOSITE DIRECTION, ON THE FIRST OBJECT
FORCE PAIR
WHEN TWO OBJECTS EXERT FORCES ON EACH OTHER
