Momentum key terms

Momentum

The product of an object's mass and its velocity, expressed as a vector quantity.

Conservation of Momentum

The principle that the total momentum of a closed system remains constant if no external forces act upon it.

momentum

Momentum is the product of an object's mass and its velocity, and it is a vector quantity.

vector quantity

In Momentum and conservation of momentum (HT only), vector quantity means a vector quantity is a physical quantity that has both magnitude and direction. Use this term when explaining (HT only) State that momentum is a vector quantity in Momentum. It helps avoid mixing up moment and force and keeps the answer anchored to AQA GCSE Physics 8463 Unit 4.5 Forces.
