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
