Introduction to Physics
What is Physics?
Physics: the study of the fundamental laws of nature
- these laws can be expressed as mathematical equations
- much complexity can arise from relatively simple laws

Temperature and Heat
What is Temperature?
By heating, the molecules of a substance move faster and have higher
kinetic energy and hence the temperature increases.
Temperature: measure of how fast the molecules move in a
substance can be defined

1. A 40.0-kg block is initially at rest on a horizontal surface. A horizontal force of
280 N is required to set the block in motion, after which a horizontal force of 120 N is
required to keep the block moving with constant speed.
