A collision where two objects bounce and move separately while kinetic energy is conserved is

• perfectly inelastic

• elastic

• inelastic

• nonexistent

The only collision in which kinetic energy is conserved is

• perfectly inelastic

• elastic

• inelastic

• nonexistent

In which collision is momentum conserved?

• perfectly inelastic

• elastic

• inelastic

• all collisions

Tags

112.45.c.7.E

The momentum before objects collide is always written as:

Tags

112.45.c.7.E

Conservation of momentum means that the initial and final momentum in a collision are

• different

• the same/equal

• impossible to determine

• always the same as the kinetic energy

Tags

112.45.c.7.E

In a two-body collision,

• momentum is always conserved

• kinetic energy is always conserved

• neither momentum nor kinetic energy is conserved

• both momentum and kinetic energy are always conserved
