This text explores essential concepts in physics, starting with motion as any physical movement or change in position. Speed is defined as the rate of movement, while velocity incorporates direction, exemplified by traveling at 50 mph north on I-75. Acceleration describes the increase or decrease in velocity over time. Lastly, energy refers to the capacity of an object or system to perform work, encompassing forms like kinetic energy and gravitational potential energy. These fundamental ideas form the foundation of classical mechanics.

What is motion? • Any physical movement or change in position or place
What is speed? • The rate at which something moves\
What is velocity? • Speed with a direction • Ex: 50 mph north on I-75
What is acceleration? • The increase or decrease in velocity over a certain period of time
What is energy? • how much work an object or system can do on some other object or system
