A hypothesis is a tentative statement which is made to try to explain a known phenomenon but whose truth value is still uncertain, whether it is true or no depends on further research. On the other hand, a theory is made up of hypothesis which have been proven to be true so far, a theory should be able to explain future phenomena successfully
Explanation and Examples
let the mass of the compressor be
mass (m):
height in x axis is (h1)
height in y axis be (h2):
Height difference: h2-h1
displacement x force:
mass x gravity x height
(m)*9.8*(height difference) = ___ J
Since gravity is forcing down, it would be negative!

By how much would its speed reading increase with each second of fall? ... Ex 3.24 For a freely falling object dropped from rest, what is its acceleration at the end of the 5th second ... Pb 3.3 A ball is thrown straight up with an initial speed of 30 m/s. How high does it go, and how long is it in the air (neglecting air resistance)?.
The tactile system is actually made up of two distinct skin senses;
protective and the discriminative system. The function of the protective system
is to alert us to harmful stimuli. The receptors of the system are the hairs of
our skin, head and genitals. The discriminative system is to show us what we
are touching, where on our bodies is touching us and what are touching us. The receptors
for his system are the hands, fingers, soles of feet and mouth and tongue.
