How did you explain conservation of momentum when a rocket ship takes off?
Momentum P of a body with mass m and velocity v is given by:P = m∙vNewton's first law of motion establishes conservation of momentum on abody as long as there is no net force applied on it.Let's assume our Rocket Ship is about to be launched from the surface ofa planet with no gravity force, so we can leave out the influence of thisforce from the discussion.At time t ≤ 0 from launch, the Rocket Ship's velocity v is zero, and soits momentum P is also zero.When the Rocket Ship starts his motion upwards, the initial system (theRocket Ship), is now conformed by two subsystems: The Rocket Ship goingup and the exhaust gases being sent down.To give a simple view of what happens, lets assume that the massof the exhaust gases is expelled at a constant velocity vg through the wholeprocess till the Rocket Ship's engine stops. Then the final condition ofmomentum would be:P = mR∙vR + mg∙vg = 0where mR and mg are the final Rocket Ship's mass and the total mass ofexhaust gases expelled respectively, and vR the Rocket Ship's final velocity.You have to realize that the vectors of velocity VR and Vg will have oppositesigns.If we now would want to include the planets gravity force, this willbe affecting the momentum of the Rocket Ship by producing an accelerationin the opposite direction of its velocity. If we now think of the originalsituation of Rocket Ship and planet at rest, when the Rocket Ship ispushing away from the planet the gravitational attraction between theRocket Ship and planet works both ways. And so the lose of momentumby the Rocket Ship because of the gravitational force is compensated bythe planets lose of momentum in the opposite direction !.
How many forces act on a ship?
There are typically three forces acting on a ship: propulsion force generated by engines to move the ship forward, drag resistance from water that opposes the motion, and buoyancy force that keeps the ship afloat by displacing water equal to its weight. Additional forces like wind, waves, and currents can also affect a ship's motion.
When a wave passes a ship at see how does the wave affect the ship?
When a wave passes a ship at sea, it can cause the ship to rock back and forth or pitch up and down, which can lead to a feeling of motion sickness among some individuals on board. The size and strength of the wave will determine the extent of the impact on the ship's stability. Ship captains often adjust their course or speed to minimize the effects of waves on the ship.
When a wave passes a ship at sea how would the wave affect the ship?
When a wave passes a ship at sea, it can cause the ship to pitch (up and down) and roll (side to side) as it moves through the wave. The ship may experience increased motion and vibrations, which can impact stability and potentially lead to seasickness among passengers and crew. Ship captains may adjust their course or speed to minimize the effects of the passing wave.
How so you explain conservation of momentum when a rocket ship takes off?
When a rocket ship takes off, it expels gas particles in one direction at high speed, causing the rocket itself to move in the opposite direction. According to the law of conservation of momentum, momentum is always conserved in a closed system. So, the total momentum of the rocket and the expelled gas remains constant before and after the launch.
What year was a rocket ship made in?
The first rocket ship, the V-2 rocket, was created in 1944 by the Germans during World War II.
Who invented the first rocket ship in 1926?
The First Liquid fueled rocket was launched by Robert Hutchings Goddard Of U.S
Why was the first rocket ship invented?
people wanted to go to the moon
Is there gravity in a rocket ship?
If the rockets are active then you will feel a gravitational force pulling you down in the direction opposite the rocket's motion. If they are off however you are weightless and you experience no gravitational force.
What was the first unmanned rocket ship put into space?
The first unmanned rocket ship put into space was the Soviet R-7 Semyorka, which was launched on August 21, 1957. This rocket successfully placed the Sputnik 1 satellite into orbit, marking the beginning of the space age.
When was Supersonic Rocket Ship created?
Supersonic Rocket Ship was created in 1972-09.
Where can I buy a rocket ship?
You can't buy a real rocket ship, but you can make a model.
Who made the first rocket ship?
The first successful rocket ship was made by the German engineer Wernher von Braun, who developed the V-2 rocket for Nazi Germany during World War II. The V-2 rocket was the world's first long-range guided ballistic missile.
What does the first rocket ship of the US look like?

Are there still people on a rocket ship heading to mars?
There is no one in a rocket ship heading to Mars.
When was Rocket Ship Galileo created?
Rocket Ship Galileo was created on 1947-05-01.
