An object’s momentum depends on both its mass and its velocity. Momentum can be expressed by the formula
where p = momentum (in g•m/s), m = mass (in g), and v = velocity (in m/s). Momentum is an important factor in analyzing collisions, especially those of automobiles. In this experiment, you will study the relationship between a car’s momentum and the distance it pushes an object during a collision. You will use a balance or spring scale to measure the car’s mass (m) and a computerinterfaced Motion Detector to measure its velocity (v). You will then calculate momentum (p) using the formula given above.
In this experiment, you will
Make conclusions about momentum.
