Linear momentum

Linear momentum ($\vec{p}$) is the product of an object's mass ($m$) and its velocity ($\vec{v}$). It is a vector quantity, meaning it has both magnitude and direction.

The formula for linear momentum is:

• $m$: The mass of the object, typically measured in kilograms (kg).
• $\vec{v}$: The velocity of the object, typically measured in meters per second (m/s). The arrow above $\vec{v}$ indicates it is a vector quantity.
• $\vec{p}$: The linear momentum, which will have the same direction as the velocity.

The standard unit for linear momentum is kilogram-meters per second ($\text{kg} \cdot \text{m/s}$).
