Which can be described as in an isolated system momentum is always conserved?
Briefly, the only way for an object to change its momentum is by transferring momentum to another object - in other words, the other object will receive a change in momentum in the opposite direction.
When a gun is firesit recoils why?
Because linear momentum is conserved. Before the shot, the momentum of (gun + bullet) is zero, so it has to be zero after the shot. The bullet gains forward momentum when fired, so the gun must gain reverse momentum in order to maintain the zero sum.
In an isolated system two cars each with a mass of 1000 kg collide Car 1 is initially at rest while Car 2 was moving at 10-ms They move off together What is their speed?
Since momentum must be conserved, they move off at a combined speed of 5 m/s. (If the masses are different, write an equation that states that momentum is conserved: momentum before the collision equal momentum after the collision).
Spaceship 1 and Spaceship 2 have equal masses of 150 kg Spaceship 1 has a speed of 0 ms and Spaceship 2 has a speed of ms They collide and stick together What is their speed?
momentum must be conserved momentum = mass*velocity initially momentum = 150*6 +150*0 = 900 kgms-1 final momentum = 300*combinedvelocity = 900 so the final velocity must be 3 ms-1
What is meant by momentum of a body?
Classically momentum is the product of the mass and velocity of an object. In relativistic mechanics, in order to be conserved, the momentum of an object must be defined as p=γm0v where m0 is the invariant mass of the object and γ is the Lorentz factor, given by γ=1/(Sqrt(1-(v/c)2) where v is the speed of the object and c is the speed of light.

What conditions must be satisfied for a theory to be valid?
One of the conditions that must be satisfied is that it must match the evidence that is provided. Next it should be able to predict things. Lastly, it's statement must be able to be verified independently.

What conditions are needed to be satisfied by a chemical reaction?
A new compound (the product) must be obtained.
What 3 conditions must be satisfied to maintain a fire?
A fire must have an adequate supply of heat, fuel, and oxygen to sustain it.

What must you have to have momentum?
you must have mass
What would be the momentum if the mass were halved?
momentum=mass * velocity if velocity remain unchanged, the momentum too will be halved ============================================== But wait! Haven't we all learned that momentum is conserved, and half of it doesn't just suddenly disappear ? If half of the mass of a moving object suddenly disconnects from the object and goes somewhere else, then half of the momentum must go along with that half of the mass, and the total momentum doesn't change. On the other hand, if Tinker-Bell flew by, waved her magic wand and sprinkled ferry dust on the moving object so that half of its mass truly ceased to exist, then in order to keep the total momentum constant, the object's velocity must double! The answer to the question is: No matter what happened to the massive moving object, or how it happened, total momentum doesn't change. It's the same today, tomorrow, and forever. Momentum of the total system is always conserved. If half of the mass is detached, you can't say the rest is the whole system. The whole system is together both halves. If both moving same velocity, momentum is divided. If that half stopped, half of the momentum goes to the force used to stop that.
