## Unit 1: Mechanics

Most phenomena in the universe involve motion and energy. The importance of studying movement becomes evident when one looks at daily activities such as physical fitness, sports and driving cars. In this unit we will begin to understand why and how objects move. In physics, the topics of motion, force, work, energy, and power are called mechanics.

## Physics1: Mechanics Objectives (or Outcomes)

By the end of this unit the student will be able to

draw d-t, v-t, and a-t graphs from ticker tape data
find instantaneous velocity from a d-t graph
state the meaning of area under a-t and v-t graphs; and the meaning of slope of d-t and v-t graphs
use these graphs to solve motion problems
describe the meaning of uniform motion and uniform acceleration
understand the difference between average velocity and average speed; calculate these quantities
solve motion problems with the 5 equations of motion
use the quadratic formula to solve for t when necessary
know the limitations on using v= d/t
