The total amount of momentum of a group of objects does not change unless outside forces act on the objects?
Momentum
The total momentum of a group of objects is conserved unless what?
outside force's act on the objects. :3
The total momentum of a group of objects is conserved unless?
b. outside forces act on the objects.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
How are momentum and interia related?
Momentum, specifically linear momentum, defined as:p = mvwhere p=momentum, m=mass and v=velocityis a vector quantity that describes an objects motion in a given frame.Inertia, or the Principle of Inertia, is an object's resistance to a change in velocity. It is pretty much summed up by Newton's First Law of motion, an object at rest/ in motion will continue at rest/ in motion unless acted upon by an outside force.Momentum and Inertia are related conceptually in the way that any object with mass has momentum, if its velocity is zero than its momentum is zero, and inertia is that objects resistance to a change in its velocity.

Can you give a sentence for momentum and roller coaster?
"In classical mechanics, momentum (pl. momenta; SI unit kg m/s, or, equivalently, ·n s) is the product of the mass and velocity of an object (p = mv). In Special_relativity, this quantity is multiplied by the Lorentz factor. Momentum is sometimes referred to as linear momentum to distinguish it from the related subject of angular moentum. Linear momentum is a vector quantity, since it has a direction as well as a magnitude. Angular momentum is a vector quantity because it gains an additional sign flip under an improper rotation. The tpseudovector momentum of any group of objects remains the same unless outside forces act on the objects (law of conservation of momentum)."Rollercoasters use momentum to keep it rolling while gravity accelerates it.Sources:Wikipedia for the quote(BTW I'm 11)
Why is momentum caused?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
What is netwon1st law?
Objects in motion tend to stay in motion unless acted upon by an outside force. Objects at rest tend to stay at rest unless acted upon by an outside force.

Why is a head-on collision likely to be more dangerous than other collisions?
Moving objects have momentum, newtons first law of motion says that unless an outside force acts on an object, the object will continue to move at its present speed and direction. Unless the objects inside the object are restrained they will continue moving at whatever speed the car is traveling even if the car is stopped by a crash.
What two factors can produce a change in momentum?
Yes, it certainly can, and we're so lucky! If it could not, then we could never stop our cars, and we would have to just jump on or off as they whizzed by.
Define law of conservation of momentum?
Total momentum in an isolated system does not change.the law of physics that states that the linear momentum does not change unless an external force acts upon itThe law of conservation of momentum explains that momentum is neither lost or gained."when two bodies collide with one another, the total energy remains constant"I COULDN'T SAY IT BETTER!That means that the total amount of momentum doesn't change. This is relevant, for example, in a collision or Newton's Cradle. (5 balls hanging on a string, when you move one to hit the other balls, there is a reaction.)"In closed system,when two bodies colloid,the total momentum before collision is equal to the total momentum after collision".A B. A. B. A. B->. ->. -> ->. ->. ->⊙ ⊙ ⊙⊙ ⊙ ⊙Consider two bodies A and B of masses m1 and m2 moving with velocities u1 and u2 respectively along the same direction.let the bodies colloid for 't' secs.During the collision A exerts a force F1 on B ans B exerts an equal and opposite force F2 on A. After collision A Moves with a velocity V2.Applying newtons second law motion ,the force exerted by the boo body B is:F1=mass of B (acceleration of B)(v2-u2)F1=m2(----------).......1tSimilarly force exerted by the body B on A is:F1= mass of A (acceleration of A)(V1-u1)F2= m1(-----------) . ........2TWhat is neat about momentum is that even if the collision is not elastic, so that kinetic energy is lost to heat, etc., the momentum is yet preserved!
What is mometum?
momentum is an object's tendency to remain in motion, or to remain at rest. momentum can also be described as the product of the mass and velocity of an object. "an object at rest tends to stay at rest unless acted upon by an outside force"
