An object with mass will have momentum if

• velocity is zero

• velocity is not zero

• all the time

Momentum can be defined as

• Bashing Power

• mass times velocity

• Bashing Power and Mass times Velocity

• True

• False

What is NOT given in the following problem

• The masses of the cars before and after the collision

• The velocity of car A before and after the collision

• The velocity of car B before and after the collision

Tags

NGSS.HS-PS2-2

What type of collision is illustrated in the problem

• Inelastic because both cars stick together

• Elastic because the cars didn't stick together after the collision

Tags

In Elastic collisions the momentum and kinetic energy are conserved

• True

• False

Tags

NGSS.HS-PS2-2

In an inelestic collision, energy is not conserved. Part of the energy is lost to heat or friction

• True

• False

Tags

NGSS.HS-PS3-4

The momenta (plural of momentum) of a closed system is conserved. Total momenta (p1 + p2 +p3 + ...) before the collision equals the total momenta (p1 + p2 +p3 + ...) after the collision

• True

• False

NGSS.HS-PS2-2

The momentum of each part in the system does NOT change after the collision alaways

• True

• False
