Friction made it difficult to discover newton's first law because under the law an object in motion will remain in motion at a constant velocity unless acted upon by an external force. Friction is an external force that slows objects in motion due to air friction (drag) and rolling resistance, making it appear as though this law is untrue.
For the first hundred thousand years of human history, the law of motion was:
A moving object with no external forces acting on it tends to stop moving. And
indeed, there is a significant portion of the world's human population who still
instinctly believe that it's the truth. Friction is what makes it seem true, but it
isn't, and it took a Newton to figure that out.
The First Law says that a moving object will continue to move indefinitely - if there is no net force. This condition (no net force) is not fulfilled if there is friction; as a result, a moving object will gradually get slower (see also Newton's Second Law).
friction pushes the opposite way the objects moving. and as for your observation question, i dont know. I think it has something to do with quantum mechanics.
newtons laws are idealised and don't involve external forces like friction and air resistance
These questions are hard, I have the same ones to answer. So difficult to find these answers.
"My name is" in Vietnamese is "Tên tôi là". But the pronunciation of these words are difficult to explain by English, I think if you travel to Vietnam, you may ask a native person or a tourist guider to teach you.
explain in brief the evolution of the computer
The U.S. had a difficult time staying neutral because they were instigated by Great Britain to join their alliance and help fight the war. It was hard to deal with the European's propaganda and the idea of "evil Germany" that caused U.S. to stay neutral.
Explain the difference between the vassals and the serfs
newtons laws are idealised and don't involve external forces like friction and air resistance
dont no
awesome looking
low friction
Because of the friction between brake pads and rim.Friction applys a forse opposed to the moving direction of rim
Speed is the magnitude of velocity (which has a direction as well).
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Explain circumstances, in which the velocity acceleration of a body is parallel?
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
Friction creates heat - heat travels by convection, conduction or radiation.
They are related through the formula distance = time x velocity (assuming constant velocity).
its realy hard to explain
