What is physical significance of linear momentum?
The same as momentum - sometimes called "linear momentum" to distinguish it from angular momentum. Linear momentum is the product of mass times velocity. It is a conserved quantity, making it very useful for certain calculations.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
What does it meanto say that momentum is conserved?
Momentum is the product of mass times velocity. The sum of (momentum x velocity) for all parts of a closed system remains constant. For instance, if two balls collide, any momentum lost by one is gained by the other (transferred to the other). Energy is NOT necessarily conserved (kinetic energy, to be more precise - any energy lost will be converted into heat, usually), so momentum is sometimes more useful for certain calculations.
What does conversation of momentum mean?
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
What is it called when momentum can be transferred but the total momentum does not change?
conservation of momentum
When is momentum not useful?
when you are skiing down a hill and you want to slow down
Why is the law of conservation of momentum useful in analyzing the collision between two bodies?
The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.
Which two theories would be useful in designing a roller coaster?
gravity and momentum

What Does it Men To Momentum is Conserved?
When momentum is conserved, the initial momentum is equal to the final momentum.
How do you find magnitude of final momentum?
Use this formula:Final momentum = (initial momentum) + (change in momentum)

What is it called when momentum can be transferred but the total momentum does not change?
conservation of momentum
The product of mass and velocity?
It's momentum.
