Elastic and Inelastic Collisions - Entry

Define momentum.

• mass x velocity

• mass x acceleration

Momentum is a vector quantity.

• True

• False

When objects stick together after collision, the collision is elastic.

• True

• False

For any collisions, elastic or inelastic, the total momentum is always conserved.

• True

• False

For any collisions, elastic or inelastic, the total energy is always conserved.

• True

• False

For any collisions, elastic or inelastic, the total kinetic energy is always conserved.

• True

• False

For any collisions, elastic or inelastic, the relative speeds are always conserved.

• True

• False
