Newton's ______ law: The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Surface resistance to relative motion, as of a body sliding or rolling.
The principle that the total linear or angular momentum in any isolated system is constant, provided that no external force is applied. This is called Conservation of _________.
Measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
Rapidity in moving, going, traveling, proceeding, or performing; swiftness.
This may be defined as the mass times the acceleration of gravity, w = mg.
The increase in speed or velocity.
The rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time
This __________ advantage is the measure of force amplification achieved by using a tool, device, or system.
The branch of mechanics that deals with pure motion, without reference to the masses or forces involved in it.
A system or _________ that is used for the observation and mathematical description of physical phenomena.
A form of motion experienced by an object or particle that is calculated near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible).
This is a measure of how much work or energy is conserved in a process.
The tendency of an object in motion to remain in motion, or an object at rest to remain at rest unless acted upon by a force.
A type of friction that keeps an object at rest.
A quantity possessing both magnitude and direction, represented by an arrow the direction of which indicates the direction of the quantity and the length of which is proportional to the magnitude.
