Question

In 1-2 sentences, explain how increasing the mass or velocity of an object affects its momentum. Give a practical example to illustrate your explanation. (2 points)

Answer 1

Momentum equals mass times velocity (p = m·v), so increasing either the mass or the velocity increases momentum proportionally (e.g., doubling mass or doubling speed doubles momentum). For example, a fully loaded truck traveling at 60 km/h has much more momentum than the same empty truck at 60 km/h, and if the loaded truck doubles its speed to 120 km/h its momentum doubles again, making it far harder to stop.
