Question | Answer |
force | a push or pull that acts on an object |
newton | the SI unit of force, equal to the force that causes a 1-kilogram mass to accelerate at a rate of one meter per second squared (1 N = 1k X m/s2) |
net force | the overall force acting on an object after all the forces are combined |
friction | a force that opposes the motion of objects that touch as they move past each other |
static friction | a friction force that acts on objects that are not moving |
sliding friction | a friction force that opposes the motion of an object as it slides over a surface |
rolling friction | a friction force that acts on rolling objects, caused by the change in shape at the point of rolling contact |
fluid friction | a friction force that opposes the motion of an object through a fluid |
air resistance | fluid friction acting on an object moving through the air |
gravity | the attraction between any two objects because of their masses |
terminal velocity | the constant velocity of a falling object when the force of air resistance equals the force of gravity |
projectile motion | the curved path of an object in free fall after it is given an inital forward velocity |
