DIstance .....ANSWER.....· Distance is a scalar quantity that refers
to "how much ground an object has covered" during its motion.
Displacement .....ANSWER.....· Displacement is a vector quantity
that refers to "how far out of place an object is"; it is the object's
overall change in position.
Position .....ANSWER.....· Position is a place where someone or
something is located or has been put. In physics, position is
usually 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 .....ANSWER.....· Speed is the distance traveled per unit of
time. It is how fast an object is moving. Speed is the scalar
quantity that is the magnitude of the velocity vector. It doesn't
have a direction.
Acceleration .....ANSWER.....· Acceleration is the rate of change
of velocity with time.
Instantenous velocity .....ANSWER.....· 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 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 .....ANSWER.....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 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 .....ANSWER.....· 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 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.
Uniform vs. non-uniform motion .....ANSWER.....· Difference
between uniform and non-uniform motion with examples. In
Uniform motion, movement of a body is along the straight line
with constant speed. In non 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
What is the difference between constant, instantaneous, and
average speed? .....ANSWER.....· constant speed is where the
