What is a quantitative observation?

Back

A quantitative observation is a measurement that involves numbers and can be quantified, such as height, weight, or volume.

What is a qualitative observation?

Back

A qualitative observation describes characteristics or qualities that cannot be measured with numbers, such as color, texture, or smell.

What does the law of Conservation of Energy state?

Back

The law of Conservation of Energy states that energy cannot be created or destroyed, it can only be transformed from one form to another.

How do you convert scientific notation to standard form?

Back

To convert scientific notation to standard form, move the decimal point to the right for positive exponents and to the left for negative exponents, based on the exponent value.

Front

What is polarization in physics?

Back

Polarization is the process where charges in a neutral object separate due to the influence of a nearby charged object.

Front

What is the definition of volume?

Back

Volume is the amount of space that a substance (solid, liquid, gas) occupies, typically measured in liters or milliliters.

Front

How do you read a graduated cylinder?

Back

To read a graduated cylinder, look at the bottom of the meniscus (the curve of the liquid surface) at eye level to determine the volume.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms or grams, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

What is the significance of the meniscus in liquid measurement?

Back

The meniscus is important in liquid measurement because it ensures accurate readings; always read the measurement at the bottom of the meniscus.

Front

What is an inference in scientific observation?

Back

An inference is a conclusion drawn from observations and prior knowledge, rather than direct measurement.
