How does a rocket travel?
A rocket moves through space by pushing exhaust gases out of its engine in the opposite direction with great force, according to Newton's Third Law of Motion. This generates thrust that propels the rocket forward. By continuously firing its engines and adjusting its trajectory, a rocket can navigate through space to reach its destination.
How is it possible for a rocket to propel itself through space?
This is possible via the conservation of momentum. A rocket ejects matter from its back and this matter carries momentum. To conserve momentum the rocket must gain an equal amount of momentum in the opposite direction. Since momentum is related to velocity this causes the rocket to move. This is basically an application of Newton's third law. You might have been confused with the situation in air. For example an airplane moves through air by pushing air past it (using its propeller). This accelerates the air, and thus increases its momentum. The airplane must therefore gain momentum in the opposite direction, and accelerates itself as well. The only difference between the airplane and the rocket is that the rocket carries the stuff it accelerates (and ejects) while the airplane can use the air that is already present all around it. Note that while this is the basic explanation, the situation with the rocket is made somewhat more complicated by the fact that as the rocket loses fuel it also loses momentum because momentum is velocity times mass and the lost fuel lowers the mass of the rocket. You might want to look up Tsiolkovsky's rocket equation if you want more information.
What is the orbital angular momentum formula and how is it used in physics?
The orbital angular momentum formula is L = r x p, where L is the angular momentum, r is the position vector, and p is the momentum vector. In physics, this formula is used to describe the rotational motion of an object around a fixed point. It helps in understanding the conservation of angular momentum and the behavior of rotating systems, such as planets orbiting the sun or electrons moving around an atomic nucleus.
What causes the earth-moon move through space?
The Earth and Moon move through space primarily due to the gravitational forces exerted by the Sun and other celestial bodies, as well as their mutual gravitational attraction. The Earth orbits the Sun while the Moon orbits the Earth, creating a complex motion where both bodies are influenced by the gravitational pull of the Sun. Additionally, the angular momentum from their formation and the conservation of momentum contributes to their ongoing motion through space.
Explain how a rocket can move through outer space where there is no matter for it to push on?
It's kinda Newton's third law. There's nothing to push against, but the conservation of momentum is such that, when a rocket throws fuel and gas out of its thrusters, in order to maintain equilibrium, the rocket moves forwards to counter the motion backwards of the propellant. I tried to make that as simple as possible, but it sounds jumbled. Lol k, here's an example: Stand in a supermarket trolley with things in it, and start throwing the contents of the trolley out behind you. You'll start moving forwards, so that the total momentum of the trolley and it's contents stays the same. That's pretty much a fundamental law of physics. So, a 200kg (for example) rocket throws 1kg of fuel/gas out at a speed of 20m/s. The rocket will start moving so to counter that 20 N/s momentum of the fuel: the rocket will move so that it has 20N/s momentum in the opposite direction. That means it'll start moving forward at 0.1m/s. See?

What role does gravity play in propelling an airplane through the air?
There are four forces acting on an airplane when it is in the sky: lift, gravity, momentum and drag. The lift makes the plane go up, gravity acts against it. The momentum of the plane makes it go forward, drag makes it go slower. Thus, gravity doesn't really even have to do with moving the plane forward.
What happen to a vehicle's momentum when it crashes into a wall?
The vehicle's momentum decreases quickly as it comes to a stop upon impact with the wall. The force of the crash dissipates the vehicle's kinetic energy, transferring it to the wall and causing damage to both the vehicle and the wall.

Why a photon cannot rest?
A photon pass through different media at different speed, but that speed always is the highest speed it can achieve at those circumstances. That is because a photon's existence not depend on its structural energy to keep its structure stable but depend on its momenta energy to keep its existence in a dynamic balanced state --- just like an acrobat riding on a single wheeled bike --- he has to swing back and forth to stay on the seat. If you are structurally complex enough, for instances, got four leg like a chair, you can stand on them still; but if you only got one leg, standing still is not the way to keep you upright --- you have to swing back and forth to achieve that. Or you can speed forward all the way or spin. In the case of a photon, it does all three of these movements --- speed forward all the way and vibrate up and down and spins. That is what happening in the photon ---it doesn't have the structural complexity to keep its existence but have to depend on a combination of its momenta energy to achieve that. The forward momentum give it the inertial energy to keep its basic structure and the vibration momentum keeps this structure dynamically stable, the spin momentum keeps the electric field and magnetic field alternatively oscillating to keep a dynamically balanced fields state. There is a dynamically balanced equilibrium point between these momenta forces, before that point is reached, the energy distribution in the photon will only keep going one way --- flow to the lower potential direction. And that direction is the forward speed momentum which not reached the saturated point. Only at that balanced point, the energy distribution becomes two way adjustment mechanism --- if the forward speed not reached the maximum (actually it is the forward momentum not reached the maximum) at that circumstances, vibration energy will be converted into forward momentum; when an outside force give an extra forward momentum, that extra momentum energy will be converted into vibration momentum. That mechanism keeps the forward momentum constant --- note: it keeps the forward momentum constant but not the speed constant, the speed constant is the result of the constant forward momentum. That is the reason when light pass through different media have different speed --- under a constant momentum, it can only achieve different speed at different resistance. In vacuum space there is no resistance so the speed can keep c --- a constant. All these strange behaviour of a photon is decided by its unique character feature --- it is the smallest unit of energy and mass that can stably exist. It doesn't have structural energy to keep its very minimal structure in a thermodynamically stable state but it has to depend on its momenta energy to do so. That is the reason it behaves different from other bigger things --- its thermodynamically stable state is always at a constant speed (result from its constant forward momentum) while other bigger things will achieve a thermodynamically more stable state by losing its momentum energy and slow down.
Does a fish have momentum?
Yes, a fish has momentum as it swims through the water. Momentum is calculated by multiplying an object’s mass by its velocity, and as a fish moves through the water, it possesses both mass and velocity, resulting in momentum.
How can linear momentum be converted to angular momentum?
Linear momentum can be converted to angular momentum through the principle of conservation of angular momentum. When an object with linear momentum moves in a curved path or rotates, its linear momentum can be transferred to create angular momentum. This conversion occurs when there is a change in the object's direction or speed of rotation.
