Simple Machines
A simple machine
What is a device that makes work easier?
Anything that takes up space and has mass
What is matter?
The ability to do work
What is energy?
A push or a pull on an object
What is force?
What is work?
A bar or rod that tilts on a fulcrum
What is a lever?
A state of matter where particles are touching, but they are still able to move around
What is a liquid?
Energy that involves motion
What is kinetic energy?
Multiple forces acting upon an object at the same time
What are combined forces?
The study of the universe and all of the rules that explain how the universe works
What is physics?
A simple machine that can help get work done with less force, over a greater distance
What is an inclined plane or ramp?
A state of matter where particles are packed together very tightly with no room to move around
What is a solid?
Energy that is stored in an object
What is potential energy?
Forces that can only act when two objects are touching
What are contact forces?
A guess based on what a scientist already knows
What is a hypothesis?
A form of inclined plane that makes it easier to push into something
What is a wedge?
A state of matter where particles are far apart with a lot of space between them
What is a gas?
Energy that is stored in atoms and released when they are split apart or joined together
What is nuclear energy?
Forces that can act even without touching the object they are acting upon
What are distant forces?
A working model of an engineering teams idea
What is a prototype?
A lever with the fulcrum at one end, the load on the other end, and the effort in the middle
What is a third class lever?
The fourth state of matter that glows in stars
What is plasma?
The energy involved in eating and breaking down foods
What is chemical energy?
A distant force that pulls objects towards each other
What is gravity?
What the typical engineering design process begins with
What is a problem?
