Acceleration occurs when an object changes both its Videos

Is this the only video relating to this topic? It only goes over ultra simple stuff need know about subtracting vectors and displacement, time graphs ect 

These are university students. Are you kidding me.

Wouldn't the black ball experience less air resistance, and air buoyancy? What if you also take into account the difference in volume which also results in different air resistance? also, rougher surface makes air to slip through easier for basketball I think? Just like the reason golf balls have pits.

My theory is this. We have all been duped by corrupt science and out conclusions are based on that standard. Now if this standard is corrupt then our conclusion is also corrupt. This means, we are all wrong because the source is wrong. The source being the corrupt science filter. My theory is this. There is no gravity but rather out down force is based on our body mass. Or matter mass. Greater mass = greater down force. Currently we are told the down force is created by spinning ball earth but if this is true, then with out own added mass, we would all die. So we need to eradicate the spin and create still. Now we are simply held down by our own weight. The next minor and subtle problem is globe. If the common science is once again corrupt on this, then the globe earth to has to be false. If we did have a stagnant globe earth, the ocean would run due to the curve. We need to remove the curve so the oceans can sit. Hence we have giant pot holes. If we have giant pot holes, we need a flat model. Or a flat earth. Now the waters sit based on there own mass and not the spinning earth standard. This to would make more sense for us. If all things are on a plate, then simply they are held down by there own mass. So there is no down force we are told is gravity. There is how ever the force created by "us".

To be precise, the black(heavier) object actually hits the ground first if it has the same size as the basketball. It is, because of the air drag. Its not a big difference in this short height example, but it is there. Try it from a 30-40m high tower and you will see the difference.

Unbalanced forces do not exist, but to understand that, we must first know what a force is at all. See it explained here: watch?v=oee0-S7ipfo
