A student drops a 6.8 kg bowling ball onto a trampoline and allows the bowling ball to bounce one time. The graph shows the vertical velocity of the bowling ball as a function of time, where upward velocity is considered positive. (a) How can this graph be used to determine the acceleration of gravity?
For parts (b) and (c), full credit will be awarded only to responses that show equations, calculations, and verbal explanations for how quantities were found from the data.
(b) What is the ball’s change in momentum as a result of being in contact with the trampoline?
(c) What average force is applied to the ball while it is in contact with the trampoline?

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

i think the answer is a, hope this is right, that would be my best guess.

i believe the answer is electric potential.

explanation:

find the sum of the two horizontal vectors and the sum of the two vertical vectors
