Q

What are accelerometers?

A

Small battery powered sensors that record acceleration in 3 spatial axes

Q

What is utilitarianism?

A

Activities that have an adverse impact on some may be justified if it leads to a net increase in welfare for the majority

39
Q

What is deontology?

A

Morality is based on whether an action is right or wrong rather than the consequences of the action
