Terms in this set (17)
An influence that tends to accelerate an object; a push or pull; measure in newtons. A vector quantity. State of motion: at rest, or moving in a uniformly line.
The vector sum of forces that act on an object.
An arrow drawn to scale used to represent a vector quantity.
A quantity in physics, such as force, that has both magnitude and direction.
A quantity in physics, such as mass, volume, and time, that has a magnitude but no direction. Can be added, subtracted, multiplied, and divided like ordinary numbers.
A state of an object or system of objects for which there are no changes in motion. In accord with Newtons 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 body in mechanical equilibrium, the vector sum of the forces on it are zero- that is, ∑F=0.
The property of thins to resist changes in motion.
Newtons first law of motion (the law of inertia)
Every object continues in a state of rest or of uniform speed in a straight line unless acted upon by a nonzero net force.
The net result of a combination of two or more vectors.
The tendency of an object to resist changes in motion.
The upward force exerted on an object. Also known as normal force.
The force due to gravity.
An object is at rest is said to be in this state.
An object that is steadily moving in a straight line path is said to be in this state.
Vectors that add together, the sum of which is their resultant.
