Laws of Motion Flashcards
When 2 forces act in the same direction :
Their strengths are added
The greater the mass of an object :
The greater it’s inertia
The force of gravity on a person or object
weight
force when two objects are rubbed together
friction
The law of universal gravitation states that any two objects in the universe that have mass, without exception:
attract each other
You can only add forces when they are
acting on the same object in the same direction
Any force that causes an object to move in a circle is called a(n)
centripetal force
a push or a pull is called a(n)
force
amount of matter in an object is called its
mass
force that pulls falling objects toward Earth is called
gravity
tendency of an object to resist change in its motion is known as
inertia
An object that orbits another object in space is called a(n)
satellite
The overall force on an object after all the forces are added together is called the ________ force.
net
Friction acts in a direction _______ to an object’s direction of motion.
opposite
An object’s inertia is a measure of its ________.
mass
The Law of Inertia is another name for which Law of Motion
First Law of Motion
Law of Action/Reaction is another name for which of Newton’s Laws?
Third Law
According to Newton’s third law of motion, the strength of a reaction force is _______ the strength of the action force.
