What are the Units of Momentum called? What happens to the Momentum if we Double the Mass? What happens to the Momentum if we Double the Velocity? What does the Law of Conservation of Momentum state? What Two Things stay the Same in an Elastic Collision? An Elastic Collision happens between what objects? What Decreases in an Inelastic Collision? Give an Example of an Inelastic Collision. Is the Momentum always Zero after an Explosion? Give Two Examples of Car Safety Features. Do Car Safety Features make the Change in Momentum Quicker or Slower? What are the Units of Momentum called? Anything that moves has momentum (see also kinetic energy). The amount of momentum which an object has depends on how fast it is moving (its velocity) and on the mass of the object. Momentum = mass x velocity. The equation is written as p = m x v where p = momentum m = mass and v = velocity. This equation is important! The units of momentum are kgm/s, called "kilogram metres per second". |
