PHYSICS DEFINITIONS QUESTIONSAND ANSWERS WITH SOLUTIONS 2024
physics - ANSWER branch of science concerned with matter and energy and the interaction between
them
motion - ANSWER change in an object's position with respect to time
particle model - ANSWER treats object as particle represented by a mass at a single point in space with
no size or shape
scalar - ANSWER quantity fully defined or described by single number
vector - ANSWER quantity described by magnitude and direction
displacement - ANSWER change in position
velocity - ANSWER rate of change of position vector
acceleration - ANSWER change of velocity with respect to time; rate of change of velocity vector
motion diagram - ANSWER composite photo showing position of object for several moments in time
kinematics - ANSWER the mathematical description of motion without regard to cause
uniform motion - ANSWER straight line motion with equal displacement over successive equal-time
intervals
non-uniform motion - ANSWER motion in which velocity is not constant
, instantaneous velocity - ANSWER speed and direction of object at one instant in time
derivative - ANSWER measure of how a function changes as its input changes
integral - ANSWER summation over infinitesimally small portions of the function
uniformly accelerated motion - ANSWER motion occurring if and only if an object's acceleration is
constant
2-D kinematics - ANSWER motion in two directions
projectile motion - ANSWER motion in which acceleration is only due to gravity
trajectory - ANSWER path followed by a projectile object
dynamics - ANSWER study of the cause of motion
force - ANSWER any influence that causes an object to undergo a change in velocity
contact force (spring, tension, normal, friction, drag, thrust) - ANSWER force that acts on an object
through physical contact
long range force - ANSWER force that exerts no physical contact on an object
principle of superposition - ANSWER net force on an object is given by the vector summation of all
individual forces
Newton's Second Law - ANSWER object of mass subjected to a force will undergo an acceleration (F=ma)
