Question

1. Which of the following equations can be used to directly calculate an object s momentum, p?

Answer 1

Answer:

p = mv

Explanation:

The momentum of an object is given by the equation:

$p=mv$

where

m is the mass of the object

v is the velocity

Since velocity is a vector, it follows that momentum is a vector as well, therefore it has a magnitude and a direction (the same as the velocity).

The SI unit of the momentum is $kg \cdot m\cdot s^{-1}$

An important law related to the momentum is the law of conservation of momentum, which states that for an isolated system (= zero net external force on it), the total momentum of the system is conserved.
