MATTER
One example of physical and chemical change
what is depends on answer
what is an example of an internal force
what is chairs or tables
how do external forces affect a structure
what is extra stress on the components
what are the major organs in the musclerskeleton system
what are bones, muscles, ligaments, and tedons
what is kinetic energy
what is energy in motion
name the states of matter
what is solid, liquid, and gas
what is an internal force
what is internal forces are forces that exist inside a structures
what is an external force
what is the external forces are the pushes and pulls
what are the major organs in the nervous system
what are Brain, spinal cord, and nerves
what are 3 types of energy
what is light, heat, electric, mechanical, nuclear, kinetic, chemical, sound, gravitational,
what is one pair of absorbing and releasing heat
what is absorbing heat=
liquid to gas, solid to liquid, solid to gas,
releasing heat=
gas to liquid, gas to solid, solid to liquid
how does this force help within a structure
what is these forces work as secret helpers, keeping parts of the structure together so they don't callaps
what is an example of an external force
what are wind, water
what are the major organs in the circulatory system
what are Heart, veins, blood vessels, and arteries
what is dissipation [energy term]
what is Dissipation is a term to describe ways in which energy is wasted
difference between chemical and physical
what is A physical change is a reversible change in the physical properties of a substance [doesn't change substance] while a chemical change is any irreversible result of a new substance
what are the 4 different types of internal forces
what is tension, shear, torsion, and compression
how does an external force influence a structure
what is for structures like buildings and bridges this force must be counteracted to prevent collapse
what are the major organs in the digestive system
what is esophagus, stomach, large intestine, small intestine,
what is lost energy
what is ''Lost energy'' means energy in a form that is not useful in that moment or for the purpose we intended
what are the properties of matter
what is Properties are used to describe matter. Properties can be measured through observation [things we touch, see, smell, hear, or taste] or by measurement.
why do engineers keep internal forces in mind while building structures
what is they keep it in mind to insure they can withstand conditions like strong winds, earthquakes, and heavy traffic
how can engineers ensure that structures can withstand natural phenomenon
what is the engineers know the forces put pressure on structures so they must account for them to ensure resilience
what are the major organs in the respiratory system
what is throat, nose, voice box, windpipes, windpipes/lungs, lungs
what is sound energy
what is movement of energy through substances in waves made when a force causes an object to vibrate and the energy is transferred in a wave
