* Momentum: The direction of momentum is the same as the direction of velocity.
* Velocity: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
In simpler terms:
* Imagine a car moving forward. Its velocity is forward, and its momentum is also forward.
* If the car reverses direction, its velocity becomes backward, and its momentum also becomes backward.
Mathematical Relationship:
The relationship between momentum and velocity is given by the equation:
Momentum (p) = Mass (m) x Velocity (v)
Since mass is a scalar (only magnitude), the direction of momentum is entirely determined by the direction of velocity.
Key takeaway: Momentum and velocity always point in the same direction.
