MOTION Flashcards
“States that An object at rest will remain at rest or an object in motion in a straight will remain in motion unless acted upon by an external unbalanced force.”
Law of Inertia
______ - the tendency of objects to resist change in motion.
Inertia
“Every object in the universe attracts every other object with a gravitational force that is directly proportional to the masses of the object and inversely proportional to the square of the distance between them.”
Newton’s Law of Universal Gravitation
______ is the measure of the amount of matter in an object.
Mass
______ is the measure of the gravitational
force on an object.
Weight
“Most objects possess inertia. An object’s inertia depends on its weight. Weight is the measure of inertia.”
TRUE or FALSE?
FALSE
“Every object possesses inertia. An object’s inertia depends on its mass. Mass is the measure of inertia.”
TRUE or FALSE?
TRUE
“States that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass”
Law of Acceleration
The formula for finding the Fnet
Fnet = M(A)
______ = net force acting on an object
Fnet
______ = mass of the object
M
______ = acceleration of the object
A
The formula for finding the acceleration
A = Fnet / Mass
A body moving in a circular path with a constant speed is in uniform circular motion.
Uniform circular motion
“States that when two objects interact with each other, the forces they exert on each other are equal in magnitude but opposite in direction”
Law of Interaction
