Measurement Flashcards
1
Q
What are systematic errors?
A
Readings that are consistently larger or smaller than the true value
2
Q
What is random error?
A
Readings that are scattered around mean value, can be reduced by averaging the readings
3
Q
What is precision?
A
Smallest division of an instrument scale, high precision implies small scatter of readings due to low random etror
4
Q
What is accuracy?
A
Closeness of a reading to the true value
5
Q
What is a vector quantity?
A
Physical quantity that has a magnitude and a direction
6
Q
What is a scalar quantity?
A
Physical quantity that has a magnitude but does not have a direction
