· Distance is a scalar quantity that refers to
DIstance "how much ground an object has covered"
during its motion.
· Displacement is a vector quantity that
Displacement refers to "how far out of place an object is";
it is the object's overall change in position.
· Position is a place where someone or
something is located or has been put. In
physics, position is usually a number on an
Position
axis. ... Position is a vector, because direction
matters. But distance is a scalar. Distance is
how far you've traveled.
· Speed is the distance traveled per unit of
time. It is how fast an object is moving.
Speed Speed is the scalar quantity that is the
magnitude of the velocity vector. It doesn't
have a direction.
· Acceleration is the rate of change of
Acceleration
velocity with time.
, · Instantaneous velocity is the velocity of an
object in motion at a specific point in time.
This is determined similarly to average
velocity, but we narrow the period of time
Instantenous velocity
so that it approaches zero. If an object has a
standard velocity over a period of time, its
average and instantaneous velocities may
be the same.
a force is any interaction that, when
unopposed, will change the motion of an
object. A force can cause an object with
A force mass to change its velocity (which includes
to begin moving from a state of rest), i.e., to
accelerate. Force can also be described
intuitively as a push or a pull
· Net force is the vector sum of forces acting
on a particle or body. The net force is a
single force that replaces the effect of the
Net force original forces on the particle's motion. It
gives the particle the same acceleration as
all those actual forces together as described
by the Newton's second law of motion.
· Difference between uniform and non-
uniform motion with examples. In Uniform
motion, movement of a body is along the
Uniform vs. non- straight line with constant speed. In non
uniform motion uniform motion, movement of a body is
along the straight line with variable speed.
In uniform motion, body covers equal
distance in equal interval of time
