For momentum to be conserved in a system it must

Momentum = m v (mass, velocity). If either one is zero, momentum is zero. So in order to have momentum, an object must have both mass and speed, in the frame of reference.

Momentum is the product of velocity and mass - so to have a "higher momentum", the object must either be more massive, or it must move faster.

the total momentum after a collision must be equal the total momentum before the collision.

No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.

Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster.Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body.

To generate momentum when hitting a birdie or shuttlecock, you must snap your wrist at the apex of your swing.

By the Law of Conservation of Momentum, the total momentum after the collision must be the same as the total momentum before the collision.

Momentum. The formula for kinetic energy is: KE = .5 * m *v^2 The formula for momentum is: p = m * v If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.

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.

For an object to have momentum, it must have mass and velocity.

Momentum = mass x velocity. It is the product of the two which you must consider.Momentum = mass x velocity. It is the product of the two which you must consider.Momentum = mass x velocity.
