  1. Name the three basic cloud types • Stratus, cumulonimbus, and cirrus • Nimbus, cirrus, stratus • Stratus, cirrus, and cumulus • Stratocirrus, cirrus, and cumulus

  2. A force can be defined as a • An attraction or repulsion • A push or a pull • Interaction between two objects • Involves momentum

  3. Momentum does not require for the object to have • Mass • Velocity • Movement in a specific direction • Acceleration
