Momentum is a fundamental concept in physics that describes the quantity of motion of an object. It is defined as the product of an object's mass and its velocity. Understanding momentum is crucial for analyzing collisions, propulsion, and many other physical phenomena.
The formula for momentum is:
Where:
Let's calculate the momentum of a car:
Given:
Step 1: Identify the formula for momentum
Step 2: Substitute the known values
Step 3: Calculate the result
Therefore, the momentum of the car is 30,000 kg·m/s or 30,000 N·s.
The following diagram illustrates the concept of momentum:
This diagram shows an object with mass (m) moving with velocity (v). The momentum (p) is the product of these two quantities, representing the object's quantity of motion.
