Energy and Scientific Models Concepts

Compression = When something gets squished Magnitude = How big or strong something is Recoil = When something bounces back after being pushed or pulled Tides = The rise and fall of the sea

Dynamic/Static Friction = The friction when things are sliding/stuck Acceleration/Deceleration = Speeding up/slowing down Stationary = Not moving Velocity = Speed in a certain direction

Bar Chart = A picture that uses bars to show information Planetary Motion = How planets move Mass = How much stuff is in something Slope = How steep something is

<p>Elastic = Something that can stretch and then go back to its original shape Friction = The force that slows things down when they rub together Motion/Time/Vertical/Horizontal Axis = The line on a graph that shows movement/time/up and down/side to side Newtons = A way to measure force</p> Signup and view all the answers

<p>Slope = Describes how steep something is Velocity = Indicates speed in a certain direction Deceleration = Refers to slowing down Planetary Motion = Describes how planets move</p> Signup and view all the answers

<p>Kinetic Energy = The energy that something has because it's moving Gravitational Energy = The energy that something has because it's high up and could fall down Elastic Energy = The energy that something stretchy has when it's pulled or squished Magnetic Force = The push or pull that magnets have</p> Signup and view all the answers

<p>Contact Force = A force that happens when things touch each other Forces that act at a distance = Forces that can push or pull without touching, like magnets Gravitational Force = The pull that makes things fall down Electrical Force = The push or pull that electricity has</p> Signup and view all the answers

<p>System = A group of things that work together Scientific Model = A way to show or explain something that we can't see or is too big or too small Net Force = The total push or pull when you add all the forces together Free-body model = A drawing that shows all the forces acting on an object</p> Signup and view all the answers

<p>Reinforce = To make something stronger Counteract = To work against something Repulsive Force = A force that pushes things apart Balanced/Unbalanced Force = When the forces are equal/not equal, so things stay still/move</p> Signup and view all the answers
