What are scalar quanitities?

Scalar quantities are quantities with magnitude only.

Differentiate accuracy from precision.

Accuracy is the degree of closeness of the measurement to the actual/real value while precision is the degree of closeness of the value from each other.

Reading a meniscus above or below eye level always gives an inaccurate reading. What kind of error is this?

Personal Error

Differentiate positive errors from negative errors.

Positive errors are committed if the reading is always too large from the actual value while Negative reading are committed if the reading is always too small.

The weather researchers didn't get the accurate rain measurement because of the strong wind that affects them. What kind of error is this?

External Error

Differentiate systematic errors from random errors.

SE gives measurement that are consistently different from the true value while the RE varied independently from one measurement to another.

What is the fundamental unit used in thermodynamic temperature?

Kelvin

The degree by which these repeated measurements agree with one another is called the

Precision

When multiplying 2 scientific numbers with different exponent, we simply multiply and _____ the exponent of ten.

ADD

When dividing 2 scientific numbers with different exponent, we simply divide and _____ the exponent of ten.

SUBTRACT

What are vector quantities?

Vector quantities are quantities with magnitude and direction.

Alice weigh 120 pounds in the weighinh scale. The next day, her sister weigh and get 120 pounds. They found that it wasn't started in 0. What kind of error will we get if the cause of faulty is the inaccurate usage of apparatus?

Instrumental Error

What do you call to the difference in uncertainty between the measured value and the standard value?

ERROR

There are 7 International Systeme (SI) fundamental units. What are they?

Kilogram, Meter, Seconds, Kelvin, Ampere, Candela, Mole

What do you call the scientific study of matter and energy and how they interact with each other.
