Answer:
Physical quantities:
A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit.
Measurement:
1 : the act or process of measuring. 2 : a figure, extent, or amount obtained by measuring : dimension.
Engine:
1 : a machine for converting any of various forms of energy into mechanical force and motion also : a mechanism or object that serves as an energy source black holes may be the engines for quasars.
Parallax error:
A parallax error is an error in reading an instrument due to the eye of the observer and pointer are not in a line perpendicular to the plane of the scale.
Motion:
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. ... One can also speak of motion of images, shapes, and boundaries.
