Chapter 3 Outline

Acceleration

Overview - This chapter illustrates mathematical modeling of quantities, introduces the pattern of change of velocity that we call acceleration, and shows the symmetrical nature of certain kinds of motion.

Objective: - Understand and calculate accelerations given variables of velocities, time, displacement and acceleration.

Start Date: - August 28th, 2006

Due Date: - September 6th, 2006

Suggested Timeframe: - Study Guides will be due Friday, Sept. 1st. , Homework: Tuesday, Sept. 5th, Lab will probably be on Friday the 1st. Test will be on Wednesday, Sept 6th.

Assignment: - Acceleration is the ratio of the change in velocity to the time interval over which it occurs.

Constant acceleration is called uniform acceleration.

The slope of the line of a velocity-time graph is the acceleration of the object.

A velocity-time graph for a uniformly accelerated object is a straight line.

Three equations relate the displacement of a uniformly accelerated object to velocity, time, and acceleration.

A position-time graph for a uniformly accelerated object is half a parabola. Position varies with the square of the time.

The acceleration of gravity is -9.80m/s2 near Earth.
