What Is Physics?
Defining the Fundamentals of Physics:
Matter and Mass
Matter:
• The physical substance that makes up objects and occupies
space
• Can be described by its various properties, such as density,
shape, and weight
Mass:
• A measure of the amount of matter in an object
• A fundamental property of an object, which does not
change, even when the object is in motion
The Concept of Work and Energy:
Moving Objects and Capacity to Do
Work
Work:
• The transfer of energy from one object to another through
a force
• Depends on the distance the force is applied and the angle
of the force
Energy:
