questions and answers 100%Correctly
verified answers latest update 2025/2026
RATED A+
Scalar - CORRECT ANSWERS A quantity with a magnitude
Vector - CORRECT ANSWERS A quantity with magnitude and direction
Accuracy - CORRECT ANSWERS How close the reading is to the true value
Precision - CORRECT ANSWERS It is determined by the range of values/measurements or the smallest
division on the measuring instrument
Systematic Error - CORRECT ANSWERS Readings that are larger or smaller than the true value by a
constant amount
Random Error - CORRECT ANSWERS Scatter in readings around the true value of the reading
Distance - CORRECT ANSWERS A scalar quantity: the sum of lengths moved
Displacement - CORRECT ANSWERS A vector quantity: the straight line distance between two points in a
given direction
Speed - CORRECT ANSWERS Rate of change of distance
Velocity - CORRECT ANSWERS Rate of change of displacement
, Acceleration - CORRECT ANSWERS Rate of change of velocity
Linear Momentum - CORRECT ANSWERS Product of mass and velocity
Equilibrium - CORRECT ANSWERS No resultant force, No resultant moment
Principle of conservation of momentum - CORRECT ANSWERS Total momentum before = total
momentum after a collision, provided no external forces act on the system
Elastic Collision - CORRECT ANSWERS A collision in which kinetic energy, as well as momentum, is
conserved
Force - CORRECT ANSWERS Rate of change of momentum
Weight - CORRECT ANSWERS Force due to a mass' position in a gravitational field
Newton's First Law - CORRECT ANSWERS A body continues at rest or constant velocity in a straight line
unless acted on by a resultant force
Newton's Second Law - CORRECT ANSWERS The force acting on an object is equal to rate of change of
momentum
Newton's Third Law - CORRECT ANSWERS Force on body A is equal in magnitude to force on body B, but
in opposite directions, and of the same type
Moment of a force - CORRECT ANSWERS The product of force and perpendicular distance to the pivot
Torque of a couple - CORRECT ANSWERS The product of one force and the perpendicular distance
between the forces
