Objectives <ul><li>describe the relationship between mass, velocity, inertia, and momentum </li></ul><ul><li>relate conservation of momentum to motion in a collision </li></ul>

Calculating Momentum <ul><li>The momentum of an object is directly related to its mass and its velocity. </li></ul>
6.
Mass <ul><li>Mass measures inertia. The mass of an object tells you how much the object resists accelerating. </li></ul>

Nothing will change speed unless acted upon by a force. If it’s sitting still, it will keep sitting still. If it’s moving fast, it will keep moving fast. Only a force can change the velocity of an object .

Velocity <ul><li>Fast objects are also difficult to stop. </li></ul>
Clipping is a handy way to collect and organize the most important slides from a presentation. You can keep your great finds in clipboards organized around topics.
