```Force and Motion Vocabulary:
Force: A push or pull on an object
Motion: Process of moving or being moved
Gravity: The force that pulls things toward Earth
Height: the measurement from base to top
Distance: an amount of space between two things or people
Surface: the outside part or uppermost layer of something
Texture: feel/appearance of a surface
Friction: the resistance that one surface or object encounters when
moving over another.
Inertia/ Newton’s 1st Law of Motion: Objects in motion stay in motion,
objects at rest stay at rest unless acted on by an outside force
Newton’s 2nd Law of Motion: Force = Mass x Acceleration
By increasing or decreasing the mass or acceleration of an object you
change the force applied by that object
Newton’s 3rd Law of Motion: For every action, there is an equal and
opposite reaction
Balanced Forces: Forces that have a net force of zero (the object is
still)
Unbalanced Forces: Forces that have a net force that is not zero
(object will move)
Chain Reaction: a series of events, each caused by the previous one
Air resistance: the force of air pushing against a moving object
Static electricity: a stationary electric charge, typically produced by
friction that causes sparks or crackling
Contact: the state or condition of physical touching
Attract: to draw by a physical force causing or tending to cause to
approach or unite; pull
Repel: to force back
