What is the equation for momentum?

It depends on exactly what relation with momentum you're asking about. We can calculate momentum as

momentum = mass x velocity

(or p=mv as a symbol equation)

We can also relate force and change of momentum. We define change of momentum as Impulse.

Impulse = Force x time

(I =Ft as a symbol equation)

Hope that helps!

The equation is Momentum = Mass of object (in kg) x Velocity of the object (in m/s). It is important for students to remember that velocity is a vector and therefore its direction can affect the sign it is given, (+ or -). Momentum itself is also a vector, and the sign it has (+ or -) also tells you the direction of the momentum.

The equation for momentum is mass of an object times velocity its velocity

(mo = ma x v )
