Question
Define momentum and explain why it is considered a vector quantity.
Answer
Momentum is defined as the product of an object's mass and its velocity, represented by the equation p = mv. It is considered a vector quantity because it has both magnitude and direction, which are determined by the direction of the object's velocity.
Explanation
This answer clearly defines momentum and emphasizes its vector nature, testing the student's understanding of fundamental physics concepts. It requires recall of definitions and an understanding of the properties of vector quantities.
Common mistake
Misunderstanding Momentum in Collisions
Students often confuse momentum with kinetic energy when explaining collision safety features.
Emphasize that momentum is conserved in collisions and is a vector quantity, while kinetic energy can change. Use examples to illustrate how momentum is transferred and conserved during collisions.
