Q

What is Newtons law?

A

Newton’s law:
Newton’s law of motion are three physical laws that describe an object and the forces acting on it, and the motion of the object in response to these forces.

Q

Define newtons 1st and 2nd law of motion

A

1st law
An object at rest will remain at rest, and an object will remain in motion, unless it is acted on by an external force.

Newton’s Second Law:
The force acting on an object is equal to the mass of that object times its acceleratio

Q

What is anti seismic technology ?

A

Anti seismic technology:
These systems involve supporting the lower levels or substructure of a building from the main upper levels (superstructure). One type of base -isolation system involves floating a building above its foundation on lead core rubber bearings

Q

What are some benefits in earthquake resistant technologies?

A

Benefits:
* Can save lives
* Limits the pressure placed on rescue and healthcare works/systems after a quake
* Can protect cultural artefacts
* Can limit the cost of rebuilding after an earthquake (economic benefits)
* Funds injected into research for continual improvement and development can advance science, other technologies (spin-offs) and provide more jobs
* Technology can also decrease sway of buildings during high winds

Q

What are some concerns of earthquake resistant technologies?

A

Concerns:
* Technology often not implemented into older existing buildings
* Can be expensive and not used in third world
* Not fail-safe: can prevent some damage but not all damage
