Introduction to Physics

Front

Define the term physics.

Back

Physics is the branch of science which studies natural phenomena and may be defined as that branch of physical science which is concerned mainly with matter, energy and energy transformation.

Front

Front

List at least 5 physicists and state contributions each made to the field.

Back

1. Albert Einstein - Theory of relativity 2. Sir Isaac Newton - Laws of motion and universal gravitation 3. Galileo Galilei - Father of modern scientific methodology 4. Aristotle - Early contributions to physics and natural philosophy 5. Michael Faraday - Electromagnetic induction.

Front

Identify and state problems in the scientific method.

Back

The scientific method involves identifying problems that need to be investigated.

Front

Formulate hypotheses in the scientific method.

Back

A hypothesis is a possible explanation based on observations.

Front

Plan and design experiments to solve specific problems in the scientific method.

Back

Experiments should use quantitative data to obtain objective generalizations and investigate one variable at a time.

Front

What is the conclusion in the scientific method?

Back

A conclusion is a solid judgment on the truth of the hypothesis based on calculations from the experiments.

Front

What is Galileo's contribution to scientific methodology?

Back

Galileo Galilei was the first to implement a scientific approach to investigate problems, often referred to as the father of modern scientific methodology.

Front

What is the equation for an object falling through a distance?

Back

The equation is s = ½kt², where k is a constant.

Front

What is the role of a control group in an experiment?

Back

A control group is used as a benchmark to measure how the other tested subjects do, ensuring that the results are due to the variable being tested.
