Physical Quantities & Measurements
Q: what is physics?
A: Physics:
Physics is based on experimental observation.
Q: what is the 2 types of observations in physics?
A: Observations in physics:
There in are two types of obser physics:
(1) Qualitative observations
(2) Quantitative observations
Q: what is the difference between Qualitative & Quantitative observations?
A:Difference between Qualitative & Quantitative observations:
Qualitative observations:
Qualitative doservations have no associated numbers. It deals with facts that can be observed
from taste water Our jive senses. Smell, hearing, touch, and sight.
Example:
colouring, textures of objects,water Keeps its level,etc.
Quantitative observations:
Qualitative observations includes numbers We can and measure also called 4 measurement. mass,
forces time, speed, torque, energy -pressure and momentum. Quantitative observations are moreuseful to the
scientists.
Q4: what is estination in phy? and how is it diff from guessing?
Estimation in physics:
Estimation is rough educated quess to the value of physical quantity by Using prior experience and
Sound physical reasoning.
How is it different from guessing?
It is different from guessing because it includes Correct physical principles, and making an informed
guess about the relevant variables, rather than Simply guessing a formula or number at random.
Q: what strateges can help improve estimation skills?
Strategies:
Some strategies that can help to improve estimations skills includes;
