How is kinetic energy and momentum similar?
Answer #1:Kinetic energy is the energy possessed by an object due to its movementor motion. Momentum on the other hand, is the quantity of motion of anobject that is a product of its mass and velocity.====================================Answer #2:Kinetic Energy = 1/2 M V2kg-m2/s2 (Newton-meter = Joule)Momentum = M V kg-m/s (Newton-second)Numerical Difference = (1/2 M V2) - (M V) = (M V) x (1/2V -1) .
Why a force of returning of the rifle is smaller than that of the bullet?
because the bullet and the rifle have equal and opposite direction,so a bullet have high kinetic energy and momentum
Is bullet knockdown power only related to velocity irregardless of weight and caliber?
No. The size-weight of the bullet also affects the knockdown power. Power, kinetic energy, force and momentum: they are all related, and each one carries a 'mass' component. It is, more expressly. the size of the Force or momentum of a moving object that determines its affect on other objects; and force and momentum are directly determined by both - the speed of the moving object and the size of its mass. As it requires a greater force to move the larger bullet in the first place, which therefore means greater energy expended to do so, so at the other end that greater energy is conserved in the larger bullet, and therefore hits its target with greater force and energy.
What energy is in a traveling bullet?
kinetic energy
Why is there not that much kinetic energy in an iceberg?
Kinetic energy is proportional to the square of the speed. If an object doesn't move quickly, it will usually not have much kinetic energy. Or it might, depending on the mass. Make some assumptions about the mass of your iceberg, and its speed, and do the calculations for the amount of kinetic energy (which is equal to 1/2 x mass x speed squared).
When a bullet is fired from a rifle?
d) they have the same momentum,but the bullet has greater kinetic energy the the rifle

When kinetic energy doubled what happens to momentum?
Momentum increases
Why does a speeding bullet and a train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.

momentum
