Force, Mass, and Acceleration: Newton's Second Law

Newton’s second law outlines how force, mass, and acceleration are related to one another. To learn more, check out the free tutorial on our website: edu.gcfglobal.org/en/newtons-...

That's it. We need sensor-driven, operator controlled electric shopping carts. The user (operator) could turn the motor on/off at-will, and the motor would be controlled by sensors that sense the total mass of the contents of the cart (in all sections) and add that to the known mass of the cart itself (including the mass of the motor), to apply the appropriate amount of force to the wheels of the cart to make them move, so the operator would have a stress-free shopping experience while still walking around and getting their exercise! Not the same as an "electric cart" used by those who have trouble walking (which includes a seat, and can only move if turned on). This would be a standard shopping cart used by shoppers who are still walking around.

Nice idea 👍🏻

Thanks! That helped a lot.

In physics, the word, “Force” as we know it, turns out to be nothing more than a
description to describe an event or an expression to express an idea like one would use the word “Love” to express
one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could
enable the initial cause of motion making it counterintuitive.
Example: Choose an object of your choices and without applying the energy from within you, try to push and pull by applying “only” the Force or Net Force.
Meaning that Energy (applied energy) is the initial origin of motion and not “Force”.
Once Energy (E) is applied, it creates what is known as Momentum (p).
When this Momentum (mass and velocity) comes in contact with an object(s),
it makes a surface contact that will enable you to push and pull. Example:
Ep=ma, Ep=mc2 and so on. Note: Ep is not to be confused as Kinetic Energy in
any way.
Momentum represents things like work, wave, gravity, light, lightning, tsunami, radiation,
earthquake, current, electricity, motion, magnetism, hurricane, etc.
Without Energy, there is no Momentum. Without Momentum, there is no surface
contact on an object(s) to push, pull, work, shaping objects, motion, gravity, magnetism, radiation,
etc. Momentum does not and cannot exist without the applied Energy that
creates it. Energy and Momentum or “Ep” is
the one and only common denominator that links all fundamental forces of
nature. Without Ep, all fundamental forces
of nature would be inert and non-existence. ~Guadalupe Guerra from Laredo Texas

0:12 🚙🕺 force mass cross acceleration .... 🤞 😅

[@amadellar]

So what will happen to the force if the overall mass of an object increases? I STILL DON'T GET IT

[@amadellar]

The amount of force applied will increase in order to keep the object moving? IS THIS RIGHT??

[@bludbeingzeto]

@@amadellar probably yes since you need such amount of force inorder to keep an object moving (an object with a heavy mass) since if you have less force and the object has more mass then the object will stop moving. (correct me if im wrong.)

In the formula F=ma, a has a time variable which means F = 0 when time = 0 and Force can not be calculated unless you provide time duration. The parameter a Acceleration is due to the Gravity and Gravity has a set vector / direction, 0 to 180 degree, in other words there is NO Acceleration if there is NO Gravity, and in Gravity direction and Time needed. Force is 0 (zero) unless you give a non zero time.This is what scientists have been hiding and the space time scam is to explain a flawed formula using the gang leader einstein. E=mc2 is also False since you can change the constant 2 to 3 or any other number, it has no effect because E has no Unit. Also all the formulas mentioned as the successor to E=mc2, has the Time variable with the value 0 (zero) which makes all the calculated Forces, Energies and Vectors Zero. Additionally einstein never wrote and published any of these formulas and no other scientist wanted to claim Fallacy.
