Name the two kinds of inertia an object could have.
Inertia of Rest
Inertia of Motion
What does velocity refer to?
speed and direction
A force used to make objects come closer to us
pull
When we shut a window, we use a ______ force.
push
Which law describes that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force?
Newton's First Law
Which law describes the greater the mass of an object, the more force it will take to accelerate the object?
Newton's Second Law of Motion
Two forces that interact with each other
force pair
A force used to make objects move further away from us
push
Forces acting upon an object are unequal and result in motion
unbalanced force
The tendency of a body to resist a change in motion or rest
inertia
What is mass?
the amount of substance that makes up an object
Which law describes "for every action there is an equal and opposite reaction"?
Newton's Third Law
Force can cause an object to change ________, __________, __________, or __________.
speed, direction, size, position
Forces acting upon an object are equal and in the opposite direction, objects remain at rest
balanced force
The tendency for an object to stay at rest until a force acts upon it is what type of inertia?
Inertia of Rest
The rate of change in the velocity of an object is called?
Acceleration
A force pulling objects down to earth’s surface is called?
gravity
When an object moves from place to place
motion
A person pushing against a wall is an example of what kind of force?
balanced
The tendency for an object to stay in motion until stopped by an unbalanced force is what type of inertia?
Inertia of Motion
The more mass an object has, the more or less for it will take to move it?
more
