Dynamics Flashcards
(42 cards)
product of both our mass and acceleration due to gravity
weight
Multiple, simultaneous forces whose pushes and pulls cancel each other out
Balanced Force
Produce a zero net force
Balanced force
the law that state objects at rest remain at rest and objects in motion continue in a __?__ line at a constant velocity unless acted on by a net external force
Straight
What does M equal
F=ma
mass
the law that state objects at rest remain at rest and objects in motion continue in a straight line at a constant velocity unless acted on by a net external force
law of inertia
SI unit for force
Newton
will initiate acceleration and a change in motion
Unbalanced Force
a force that accelerates an object toward the center of a circular path
centripetal
What does the F stand for
F=ma
Force
A force that acts only when one object touches another
Contact Force
F=ma is the equation for?
Law of acceleration
force = mass x acceleration
what is Newton represented with
Capitol N
Static Friction
No motion
Produces a net force
Unbalanced force
A force that acts between objects that are not touching; also called force at a distance
Field Force
a force that acts in a direction that is perpendicular to the surface where the 2 objects make contact
normal force
The law that states that for every action there is an equal and opposite reaction in different directions
Law of action - Reaction
the net force is the __?__of the forces on an object
sum
The principal forces are
Gravital, Magnetic, and electric
a pulling force that is transmitted through a rope chain or similar object
tension
does mass or weight change
weight
a field force that acts between the masses of any 2 objects
gravity
the law that state objects at rest remain at __?__ and objects in motion continue in a straight line at a constant velocity unless acted on by a net external force
rest
