JHHS 1D Motion Qualitative Review

What allows us to call objects "still" or "motionless" in our physics class when we know all objects on Earth are on a rotating planet, revolving around the sun, which is in turn spinning around the center of the Milky Way galaxy AND that galaxy is rocketing through the universe?

• Although there are many dynamic elements of our place in the universe, these objects truly are still.

• These factors are so small that they are insignificant to the motion of a normal object on earth.

• The object's motion is still relative to the space it is within

• Nothing can be considered still or motionless, as objects are also dynamic at the atomic level

If an object is moving in the positive direction while experiencing a positive acceleration

• The object is slowing down

• The object is speeding up

• The object is moving at a constant velocity

• The object is not moving
