1
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.
3
Surface resistance to relative motion, as of a body sliding or rolling.
4
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 _________.
5
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.
10
Rapidity in moving, going, traveling, proceeding, or performing; swiftness.
11
This may be defined as the mass times the acceleration of gravity, w = mg.
13
The increase in speed or velocity.
15
The rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time
17
This __________ advantage is the measure of force amplification achieved by using a tool, device, or system.
18
The branch of mechanics that deals with pure motion, without reference to the masses or forces involved in it.
19
A system or _________ that is used for the observation and mathematical description of physical phenomena.
20
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).
21
This is a measure of how much work or energy is conserved in a process.
23
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.
25
A type of friction that keeps an object at rest.
27
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.
