100% Correct Answers Already Graded A+
Q: DIstance
Ans: · Distance is a scalar quantity that refers to "how much ground an object
has covered" during its motion.
Q: Displacement
Ans: · 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.

Q: Position
Ans: · 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.
Q: Speed
Ans: · 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.
Q: Acceleration
Ans: · Acceleration is the rate of change of velocity with time.
Q: Instantenous velocity
Ans: · 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.
Q: A force
, 2 Exampromax - Stuvia US
Ans: 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
Q: Net force
Ans: · 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.
Q: Uniform vs. non-uniform motion
Ans: · 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
Q: What is the difference between constant, instantaneous, and average
speed?
Ans: · constant speed is where the speed is the same throughout and
instantaneous speed is speed given at any moment and average speed is a total
distance traveled divided by the amount of time it took to travel it.
Q: Newtons Laws
Ans: Newton's first law states that every object will remain at rest or in uniform
motion in a straight line unless compelled to change its state by the action of an
external force. The second law states that the acceleration of an object is
dependent upon two variables - the net force acting upon the object and the mass
of the object.
The third law states that for every action (force) in nature there is an equal and
opposite reaction.
Q: Coefficient of friction
Ans: · A coefficient of friction is a value that shows the relationship between two
objects and the normal reaction between the objects that are involved. ... The
coefficient of friction depends on the objects that are causing friction. The value is
usually between 0 and 1 but can be greater than 1.
Q: Torque
