Newtons 3rd Law?

Question

Don't you think that Rocket is flying due to Newton's 2nd law rather than 3 rd law

Sorry,

Question is wrong.

I am asking about Netwon's first law rather than 3rd law

Answer 1

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Answer 2

All of Newton's laws apply to rocket flight. The third law gets all the press because it is what allows the engine to exert a force on the rocket even in the vacuum of space.

Answer 3

Just to beat a dead horse...all of Newton's laws apply to motion, and that includes rocket motion. However, the first law (an object in motion tends to stay in motion, object at rest tends to stay at rest) isn't quite as relevent because rockets propel burning gas out one end and due to Newtons 3rd law they are sent flying in the oppisote direction.

Answer 4

The first law implies an object doesn't like change simply for the sake of change.

The second law attempts to predict a measure of change IF a specific other change occurs.

The third law proves what goes in, must come out.




So, the second law would go further to explain why the rocket flies as it does.

Answer 5

Newton's first law of motion is often stated as

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Answer 6

Different parts of a rocket flight are related to different laws of motion.
1) It is sitting waiting to be launched (1st law)
2) It is being launched, (2nd Law)

Answer 7

There are three basic concept relating to motion that have a common value. They are:

hf = E, This is the value of electromagnetic energy and why its energy value changes as its frequency changes.

hf = mk, This concept is a continuation of the above. Because mass is composed of electromagnetic energy, the same values apply to the energy comprising the mass as well as this energy apart from being formed into a mass.

hf = c, In that all forms of energy have a frequency, this energy form also is subject to the frequency value.

What you are interested in is the second value. This describes mass as changing length according to the kinetic energy contained within. The greater the energy within the mass in a single dimension, the greater lines of frequency in a given distance.

What happens for this to happen is that energy at a right angle to direction of travel decreases in proportion to the increase in a single dimension. This is seen in that mass moving at the speed of light minus 2 mps, has a potential of only 2 mps in any right angle direction. At the speed of light this would drop to zero energy potential at a right angle to direction of travel.

You can see that the reason mass moves, is due to an internal energy imbalance. The energy within the mass (its frequency) remains within the mass till that energy is able to be communicated to another mass.

Answer 8

In any interaction between two bodies, the force applied by the first body on the second is equal and opposite to the force applied by the second body on the first.

in a simple way it can be said as Ation and reaction are always equal and opposite. F1=F2

Answer 9

i think for rocket three laws are acting togather.
1st when rocket is lanched 3rd law is acting
then 2nd&1st are applied.

Answer 10

every object continues to be in state of rest or continues motion unless disturbed by some external force
