Newton's Law & Friction Crossword Puzzle

a push or pull that one body exerts on another
the SI unit of force--it's equal to the force that will give a mass of one kilogram an acceleration of one meter per second
unbalanced forces that are not opposite and equal
a force that opposes the motion of objects that touch as they move past each other
the friction force that acts on objects that aren't moving
a force that opposes the direction of motion of an object as it slides over a surface
the force that acts on rolling objects
opposes the motion of an object through a fluid
if no net forces acts on a system, then the total momentum of the system doesn't change
is the product of an object's mass and its velocity
the motion of a falling object after it is given an initial forward velocity
the fluid friction action on an object moving through the air
force of attraction between any two objects in the universe
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration
tendency of an object to resist any change in its motion
when gravity is the only force acting on an object
a body's relative mass or the quantity of matter contained by it, giving rise to a downward force
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
the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
when one object exerts a force on a second object, the second object exerts an equal but opposite force on the first
