If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.

How does the first and third law of motion apply to a rocket launching?

1st. The rocket sets still until a force, burning fuel, causes a change in motion. 2nd. F=ma The force of the burning fuel causes an acceleration of the rocket. 3rd. Action/reaction. The action of hot burning gases leaving the rocket causes a reaction, which is the motion of the rocket in the opposite direction. Note: The exhaust does not need to hit the ground to cause the reaction. A rocket engine ignited in outer space will cause a change in the motion of the rocket.


Which law of motion is used to explain how a rocket takeoff?

The third law applies here. For every action there is an equal and opposite reaction. When the rocket fuel is ignited it exerts enormous thrust directed downwards. If the rocket is not constrained to the launching pad (with very very heavy restraints) it sees no other way to nullify the enormous thrust but to set itself in motion. Soon as more fuel burns, the rocket accelerates. As a side, if the rocket was restrained with very heavy agents, these agents (in the form of nuts and bolts or whatever) will have to bear the thrust of the rocket engine.


How does a rocket launch demonstrate Newtons Rd law?

A rocket launch demonstrates Newton's third law of motion when the rocket propels itself upward by expelling exhaust gases downward. As the rocket fires its engines, it pushes the exhaust gases downward with a force. Simultaneously, the gases pushing downward create an equal and opposite force that propels the rocket upward, following Newton's third law that every action has an equal and opposite reaction.

What is the action force during a rocket launching?

During a rocket launching, the action force is the thrust generated by the rocket engines expelling high-speed gases in the opposite direction of the desired motion. This thrust pushes the rocket upward by exerting a force on the ground, following Newton's third law of motion.


How the law of interaction being applied on rocket launching?

The law of interaction states that for every action, there is an equal and opposite reaction. In the context of rocket launching, this law is applied as the rocket pushes exhaust gases downward with force (action), causing the rocket to move upward (reaction) in the opposite direction. This principle underlies Newton's third law of motion and is fundamental to the physics of rocket propulsion.

Which law of motion explains how a rocket is launched?

The third law of motion, also known as Newton's third law of motion, explains how a rocket is launched. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket launch, the rocket propels exhaust gases downward, which in turn creates an upward force that lifts the rocket off the ground.

Which law of motion is used to explain rocket propulsion?

The third law of motion, known as Newton's third law, is used to explain rocket propulsion. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket, hot gases are expelled backward, causing the rocket to move forward in the opposite direction.

What law of motion is illustrated by a rocket taking off?

The law of motion illustrated by a rocket taking off is Newton's Third Law of Motion which states that for every action, there is an equal and opposite reaction. The rocket propels itself upward by expelling gases downward, creating a reaction force that propels it forward and upward.


How does a rocket represent newtons 3rd law of motion?

A rocket represents Newton's 3rd law of motion by demonstrating that for every action (the force of the rocket pushing exhaust gases downward), there is an equal and opposite reaction (the force pushing the rocket upwards). This is why the rocket propels itself upwards as it expels gases downwards.


What kind of newtons law of motion is illustrated if the force that accelerates a rocket into outer space is exerted on the rocket by the exhaust gases?

For every action, there is an equal and opposite reaction (Newton's third law of motion)..
