Science Vocab 3

Physics words

motion when an object's distance from another set object changes
reference point a place or object used for comparison to determine if an object is in motion
average speed the overall rate at what the object moves
instantaneous speed the speed an object travels at a given time
speed the distance an object travels per unit of time
velocity speed in a given direction
slope the steepness of a line on a graph that is equal to its vertical change divided by its horizontal change
acceleration the rate at which velocity changes
force a push or pull exerted by an object
unbalanced force forces that change an object's motion
balanced force equal forces acting on an object in opposite directions
newton a unit of measurement that equals the force to move 1 kilogram of mass at a meter per second
net force the overall force on an object when all the forces on it are added
friction the force one object exerts on another when they rub against each other
static friction force that acts upon nonmoving objects
gravity the force that pulls objects together
sliding friction when an object slides on a solid and creates friction
rolling friction when an object rolls on a solid and creates friction
fluid friction friction that occurs when an object moves through a fluid
air resistance the fluid friction in the air
free fall the motion of an object where the only force acting on it is gravity
terminal velocity the greatest velocity falling object can achieve
inertia when an object resists change in its momentum
momentum the product of the mass and velocity
Law of Conservation of Momentum when all outside forces are absent, the total momentum of objects that interact does not change.
