Final answer:
The momentum of a moving object is determined by the formula momentum = mass × velocity. The correct method to find momentum is to multiply the object's mass by its velocity (option D). Momentum is a vector quantity, meaning it includes both magnitude and direction.
Step-by-step explanation:
The momentum of a moving object can be found by using the formula: momentum (p) = mass (m) × velocity (v). To determine the momentum of an object, you multiply its mass by its velocity. Remember that mass is a measure of the amount of matter in an object and velocity describes the speed and direction of its movement. Momentum is a vector quantity, which means it has both magnitude and direction, and its unit is kilogram meters per second (kg·m/s). Therefore, to answer your question, the correct option is D. By multiplying its mass by its velocity.
Momentum is directly proportional to both the mass of the object and its velocity, meaning that greater mass or higher velocity results in greater momentum. It's crucial to note that velocity includes both speed and direction, so momentum also depends on the direction of the object's motion.
