Mrs. Patelunas' Forces, Friction and Momentum Vocabulary
Question | Answer |
---|---|
kinetic friction | the friction caused by moving objects |
static friction | the friction that exists between two stationary objects |
force | a push or a pull that gives energy to an object |
momentum | the product of an object's mass and its velocity |
Newtons | the unit of force |
Net Force | the total of all the forces acting on an object |
Law of Conservation of Momentum | the total momentum of a group of objects remains the same after collision unless forces like gravity or friction act on the objects. |
balanced forces | the net force acting on an object is zero |
unbalanced forces | the net force acting on an object is not zero |
sliding friction | the type of kinetic friction that occurs when two solid objects rub against each other |
fluid friction | the type of kinetic friction that occurs when objects move through a liquid or a gas |
rolling friction | the type of kinetic friction that occurs when an object rolls over a surface |
