Momentum Internet Lab Momentum and Collisions Name: Date: Period: Website: Play with the Sims Physics Motion Collision Lab Introduction: When objects move, they have momentum . Momentum, p, is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum, p, is kg·m/s. During a collision objects transfer momentum to each other, resulting in different motions than before the collision. In this activity you will study the motion colliding objects. momentum = m × v ELASTIC Collisions 1 1before 2 2before 1 1after 2 2after m v + m v = m v + m v 1. What defines a collision as being elastic? 2. Simulate the four elastic collisions below. Complete the table using math formulas and the simulation.

Two objects with the same mass move toward each other with the same speed and experience an elastic collision. 2
