FORCES
what's a force
a force is a push or pull.
what are dynamic forces
they are often into a goal past to someone or rain or roof.
a solid to liquid.
melting
what are the three types of matter?
solid, liquid, gas
what is matter
matter is a mass that can take up space.
internal forces
the internal forces are caused by one of a part a structure that is acting on other part of a structure (forces come from within the structure)
you can classify structures by its
function, construction
freezing
what is a solid
solid is a packed particles
what are the tiny particles in matter?
atoms
external forces are pushes and pulls that come outside the buildings.
what are external and how do they affect strutures
classify structures with
solid, frame, shell
liquid to gas.
condenstation.
what is a gas
a gas is a particle that are not tightly packed together
what would happen if solid turns into a liquid?
it is absorbing heat
dynamic forces
someone into a goal post, rain or roof, wind on tower, runners on track
what is a solid
they are a large of masses
sublimation
solid to liquid.
what is a liquid
something particles that are not packed together
what happens if you turn liquid to solid?
releasing heat
what are the examples for the internal forces and the external forces?
internal EX: compression, tension, torsion, shear
external EX: wind, water gravity, movement of the earth, people walking
describe the shell and frame
shell: shape hollow curved frame
frame: a skeleton of materials
gas to solid.
deposition
the examples of solid liquid and gas
liquid: beverages, drinks, water
solid: materials
gas: gasoline, smoke.
what happens if i turn gas to liquid
releasing heat
