Motion Unit Vocab

When the distance between 2 objects changes

• intertia

• motion

• reference point

• acceleration

movement in relation to a frame or reference point

• relative motion

• motion

• reference point

• velocity

Place or object used for comparison to determine if something is in motion

• Newton's 1st Law

• Newton's 2nd Law

• relative motion

• reference point

An object in motion stays in motion, an object at rest stays at rest--unless acted upon by an unbalanced force

• unbalanced force

• balanced force

• Newton's 1st Law

• Newton's 2nd Law

F = ma ... force equals mass times acceleration

• Newton's 1st Law

• Newton's 2nd Law

• velocity

• reference point

resistance to an object’s change in motion

not a force

• acceleration

• inertia

• relative motion

• Newton's 1st Law

a change in speed and/or direction of a object

• velocity

• relative motion

• acceleration

• law

creates motion

• unbalanced forces

• balanced forces

• velocity

• acceleration

An object that will have no motion or an object that will move in the same speed and direction

• unbalanced forces

• balanced forces

• velocity

• acceleration

speed in a given direction

• law

• relative motion

• motion

• velocity
