Introduction to Physics

Physics is concerned with which of the following matters?

• applying physics prinicples

• describing the physical world

• making predictions about a broad range of phenomena

• all of the above

After making observations and collecting data that leads to a question, a physicist will then

• formulate and test hypotheses by experimentation

• state conclusions

• interpret the results

• revise the initial hypotheses

How many variables may be tested legitimately in any one experiment?

• as many as a physicist can handle

• three

• one

• five

Scientists test a hypothesis by

• formulating questions.
• designing models.
• doing experiments.
• drawing conclusions

An important science skill is critical thinking. This means

• thinking logically to solve a problem.
• discovering the shortcomings of others.
• knowing when something is very important.
• testing a hypothesis during an experiment.

A mathematical representation of an object or event is a

• model
• variable
• control
• theory

Which of these is not within the scope of Physics

• Matter and energy

• Nature and its phenomena

• Sounds and Waves

• Animals and their anatomy

Select all that is true about models

• A model is a representation of a phenomenon in nature

• A model is often modified as scientists gain more knowledge

• A model can replace reality

• A model can simplify complex systems

In Greek, Physics means

What is physical science?

• The study of Scientific methods

• The study of knowledge

• The study of nonliving matter

• The study of living things.
