...100% Correct Ans...
PHYSICS SEMESTER 01 ASSIGNMENT WITH 100% CORRECT
ANSWERS
a=F/m
ans:>The mathematical formula associated with Newton's Second Law
of Motion
a curve on a position - time graph
ans:>Shows an object with changing (accelerated) motion
a horizontal line on a position - time graph
ans:>Shows an object at rest
acceleration
ans:>The amount and direction that the instantaneous velocity changes
in a unit of time
accuracy
ans:>the closeness of a measurement to its actual or theoretical value --
indicated by a statement of error
action force
ans:>One force in a force-pair; it is the cause of the force-pair. (Note: in
some cases, like gravitation, this is impossible to determine.)
,air resistance
ans:>the fluid friction experienced by objects falling through the air.
an angled line on a position - time graph
ans:>Shows an object with constant motion
Applied force
ans:>a force which is applied to an object by a person or another object
at rest
ans:>The state of an object when it is not in motion with respect to a
particular reference point
average acceleration formula
ans:>change in velocity/elapsed time
average acceleration
ans:>The acceleration experienced by an object over a large period of
time
average net force
ans:>the type of force found in the formula F = ma.
average of velocities formula
ans:>the sum of the initial and final velocities/2
average velocity formula
ans:>total displacement/elapsed time
average velocity
ans:>the number of meters moved in one second in a particular
direction, found by dividing the displacement in a direction by the
elapsed time
, axis
ans:>a fixed reference line for the measurement of coordinates
Balanced forces
ans:>Equal forces acting on an object in opposite directions
balanced forces
ans:>Forces along one dimension -- e.g., horizontal or vertical -- that
oppose each other in such a way that their effects are negated
Black hole
ans:>A concentration of mass that results from gravitational collapse of a
star, near which gravity is so intense that not even light could escape.
C.O.D.S.
ans:>The acronym which will help you remember the four things all
forces must have: a cause, an object on which they work, a direction in
which they act and a size
Center of mass
ans:>The point in an object at which we can imagine all forces act
centrifugal force
ans:>a pseudo-force that is blamed for pushing objects to the outside of
a turn; it is NOT a force, because it does not have a cause. Instead,
objects attempt to follow straight-line paths and a force must be applied
to change that path (see Newton's first law of motion)
change in momentum
ans:>the amount and direction of a change in the either the mass or
velocity or both of an object.
changing motion
