The normal force is also called

______ is the force that is the pull of gravity

Physics is the most basic science bc

When she releases one arm and hangs from one arm alone, the tension is

reasonable explanation for observations that can be tested&evaluated with additional experiment

P says “a horizontal clothesline cannot support his weight bc the tension required is toolarge”

Which of the following would not be considered a part of the scientific method

When equilibrium exists, the forces are all

Equilibrium applies to

An idea that has been tested over&over again& is thought to be the best explanation at the time

Physics is the study of

The scientific method was formulated by

If she spreads her arms out so her arms are angled rather than vertical as she hang. Tension

Another way to distinguish between force and net force is

_____ is the force that balanced due to gravity

In The scientific method physicists formulate and objectively test hypothesis by

The idea that science can change as more ideas and tech improve

When equilibrium exists , the numerical net force is

The further apart her arms, the _________ the tension in her arms

_____________ is a stretching force

The steps of the scientific method are best ordered as

The difference between force and net force is

The purpose of the scientific method is to

______ is a close agreement of observations by a competent observers

On the uneven bars, a gymnast hangs w both arms practically vertical, the tensions on each arm

object can be in mechanical equilibrium whether at rest or moving w constant speed in straight

Vectors have
