if one mass collides elastically with another mass, causing the stationary mass to begin moving with the velocity of the first and the first mass to stop moving altogether, then the masses are equivalent.
what type of collision is defined by some kinetic energy converted into other forms?
Do masses with large velocities always have larger momentum? larger masses?
T/F Falling masses gain downward velocity as they fall due to gravity. Since their velocity increases so does their momentum downward.
yes; yes; impulse
is momentum a vector quantity? what about the change in momentum? what do you call a change in momentum?
T/F bending your knees when landing decreases momentum, ultimately preventing you from serious injury. this is because change in momentum occurs over a larger amount of time.
T/F non conservative forces are at work in elastic collisions.
is momentum conserved in 2D collisions?
most collisions occur in one dimension
