Edpuzzle (Bill Nye: Momentum) Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is momentum a product of? Momentum is the product of an object's mass and velocity. How does increasing the mass of an object affect its momentum? Increasing the mass increases the momentum if the velocity remains constant. What happens to momentum when two objects collide and stick together? The total momentum is conserved, meaning the momentum before the collision is equal to the mom...
