science
strength or energy as an attribute of physical action or movement.
force
the resistance created by any two objects when sliding against each other.
the maximum velocity (speed) attainable by an object as it falls through a fluid
pulls objects with mass toward each other
force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second
occurs when a wheel, ball, or cylinder rolls freely over a surface,
the motion of an object thrown or projected into the air, subject to only the acceleration of gravity
within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed
any force which causes a change in direction of velocity toward the center of the circular motion.
the sum of all the forces acting on an object
occurs between fluid layers that are moving relative to each other
a tendency to do nothing or to remain unchanged.
The direction of magnetic flux produced by a permanent magnet is always from N-pole to S-pole
the resistance that one surface or object encounters when moving over another.
a kind of friction (a force that opposes motion) which occurs between air and another object
a coherent, typically large body of matter with no definite shape.
a fundamental interaction that confines quarks into proton, neutron, and other hadron particles.
a force that keeps an object at rest
the universal force of attraction acting between all matter
the amount or quantity of heaviness or mass
a fundamental force of nature that underlies some forms of radioactivity
