The state in i beg your pardon one object's distance from an additional is changing.

You are watching: The rate at which an object moves is called

reference pointA location or an item used because that comparison to identify if things is in motion.
distanceThe size of the path in between two points.
international device of unitsA mechanism of measurment based upon multiples of ten and also on created measures of mass, length, and time.
speedThe distance an item travels per unit the time.
average speedThe as whole rate of speed at which things moves: calculate by dividing the total distance an item travels by the full time
instantaneous speedThe rate of an item at one prompt in time.
velocitySpeed in a provided direction.
slopeThe steepness that a graph line; the ration of the vertical change (the rise) come the horizontal change (the run)
accelerationThe price at i beg your pardon velocity changes.
forceA press or a traction exerted on an object.
newtonA unit of measure up that equates to the force required to accelerate 1 kilogram the mass in ~ 1 meter per 2nd per second.
net forceThe in its entirety force on an item when every the individual forces acting on that are included together.
frictionthe force that 2 surfaces exert on each other once they rub against each other.
sliding frictionFriction that occurs once one solid surface slides over another.
static frictionFriction the acts between objects that are not moving.
fluid frictionFriction the occurs as an object moves through a fluid.
rolling frictionFriction the occurs when an item rolls over a surface.
gravityThe attractive force in between objects; the force that moves objects downhill.
massThe amount of issue in one object.
weightA measure up of the pressure of gravity acting on one object.
inertiaThe tendancy of an object to withstand a change in motion.
momentumThe product of an object's mass and also velocity.

law of preservation of momentumThe dominion that in the lack of exterior forces the total momentum the objects that interact does no change.
