BINGO Unit 4 Review!
A push or pull, or anything that causes a change in motion of an object
The force of gravity exerted on an object. It changes if you are on the moon.
A type of structure in which a skeleton of materials supports the weight of the other parts. Ex. A chair
Kilogram • The primary standard for mass- the unit used to measure mass. How many newtons does 1 kg weight on Earth?
A process that uses a different material to join two materials together by melting?
The weight of a structure upon itself- a type of external force
When a layer of material is pressed or glued onto other layers
This ensures that a structure has extra strength to support more load than normal
An object with a definite size and shape, which fulfills a specific purpose or function. The parts have a specific arrangement that stays the same
An example of this is the motion of a bicycle wheel- the reason you can ride with no hands sometimes!
When two parts are pressed in opposite directions at the same time. Ex avalanche
This internal force crushes a material by squeezing it together
The amount of matter in a substance; often measured with a balance
The point at which all of the gravitational force of an object may be considered to act. It needs to be balanced in a stable structure
A structure that is made by piling up materials. Example: pyramid
There are two types of these; solvent-based, which harden as they dry out, and thermosetting, which harden as they cool
A force on a structure that is not part of the structure itself. Ex. Wind, weight of people, collision
