Conceptual Physics Ch1-4 (Newton's Laws of Motion)
Terms in this set (16)
The quantity of matter in an object. More specifically, it is the measure of the inertia or sluggishness that an object exhibits in response to any effort made to start it, stop it, deflect it, or change in any way its state of motion.
The property of things to resist changes in motion.
Newton's first law of motion (the law of inertia)
Every object continues in a state of rest or uniform speed in a straight line unless acted on by a nonzero force.
In the simplest sense, a push or a pull.
Newton's Second Law
The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
Newton's third law
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
The resistive force that opposes the motion or attempted motion of an object either past another object with which it is in contact or through a fluid.
The vector sum of forces that act on an object.
An arrow drawn to scale used to represent a vector quantity.
The net result of a combination of two or more vectors.
The state of an object or system of objects for which there are no changes in motion. In accord with Newton's first law, if an object is at rest, the state of rest persists. If an object is moving, its motion continues without change.
For any object or system of objects in equilibrium, the sum of forces acting equals zero.
The speed at any instant.
The total distance traveled divided by the time of travel.
The force upon an object due to gravity, mg.
The quantity of space on object occupies.
