· Distance is a scalar quantity that refers to "how much
DIstance
ground an object has covered" during its motion.
· Displacement is a vector quantity that refers to "how
Displacement 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
Position a number on an 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 is the scalar
Speed
quantity that is the magnitude of the velocity vector. It
doesn't have a direction.
· Acceleration is the rate of change of velocity with
Acceleration
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
Instantenous velocity period of time 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 mass to change its velocity (which
A force
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 original forces on the
Net force
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 straight line with constant
Uniform vs. non-uniform
speed. In non uniform motion, movement of a body is
motion
along the straight line with variable speed. In uniform
motion, body covers equal distance in equal interval
of time
· constant speed is where the speed is the same
What is the difference
throughout and instantaneous speed is speed given at
between constant,
any moment and average speed is a total distance
instantaneous, and
traveled divided by the amount of time it took to
average speed?
travel it.
