Newton's 3 Laws of Motion (Motion, Forces, Dynamics) HPS
Terms in this set (20)
the result of unbalanced forces, change in speed and direction
a push or a pull, with both strength & direction
resistance to change
distance traveled per unit time
speed of an object in a specific direction, the rate at which a position changes
amount of matter in an object or the measure of inertia in an object
the rate that velocity changes over time
measure of gravitational attraction or force or gravity pulling one object toward the center of another object
force that opposes motion between 2 sources
the force that pulls on objects and causes acceleration if the objects are not balanced by an opposing force
First Law of Motion
"An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force."
Second Law of Motion
"The greater the mass the greater the amount of force needed to accelerate the object. F=MxA"
Third Law of Motion
"For every action, there is an equal and opposite reaction."
sum of all forces acting on an object
unit of force, the force required to accelerate 1kg of mass at 1m per second
keeps an object moving with the same speed and direction (including at rest), net force is zero, no change in motion
an objects speed and direction will change, net force is NOT zero, change in motion
a place or object used for comparison to determine if something is in motion
distance and direction of an object's change in position from the starting point
two forces exerted on two different objects from an action-reaction pair
