compares a measurment to the real of accepted value

potnetial energy

Stored energy due to position

air resistance

Opposes the mtion of objects that moves through air

net force

Two or more forces acting on an object at the same time


Change in velocity divided by the time for the change to occur


The direction and distance of an objects final position from its initial position

control systems

a device that monitors a system

centripetal force

Net force exerted toward the center of a curved path


Occurs when what the scientists expect changes in the way the results are viewed

dependent variable

The amount of growth in an experiment


A factor that can express can cause a change in the results of an experiment


The tendency of an object to resist motion


The application of science to help people

independent variable

The variable you change to see how it will affect the dependent variable

scientific law

what happens in nature, seems to be true all the time


the SI energy unit


The ability to do work

balanced force

Forces on an object that are equal in size and opposite direction


a push or pull on an object
