To calculate the momentum of an object, you need to know both its mass and velocity. The formula for momentum is given by the equation:

p = mv

Where p represents momentum, m is the mass of the object, and v is its velocity. It is important to note that momentum is a vector quantity, meaning it has both magnitude and direction.

Consider the following example: A car with a mass of 1000 kg is moving at a velocity of 20 m/s. To calculate its momentum, simply multiply the mass and the velocity:

p = 1000 kg x 20 m/s = 20000 kg⋅m/s

It is crucial to keep the units consistent throughout your calculation.
