Acceleration and Kinematic Equations

We are back at the Porsche Experience Center Atlanta track to learn all about acceleration. Kinematic equations are introduced as we solve for stopping time and displacement.

Learning Objectives

-Define average acceleration as the rate of change of velocity divided by time elapsed.

-Differentiate between average acceleration, constant acceleration, and instantaneous acceleration.

-Find average acceleration and instantaneous acceleration from a velocity versus time graph and an acceleration versus time graph.

-Understand what it means when acceleration has a negative value with respect to motion relative to the positive direction.

-Explore kinematic equations and understand how they can help in solving problems with constant acceleration.

Vocabulary

average acceleration - the rate of change of velocity divided by time elapsed. The SI unit for acceleration is meters per second squared (m/s2).

constant acceleration - acceleration that does not change.

instantaneous acceleration - acceleration at a given moment in time.

kinematics - the science of describing the motion of an object.

Georgia Standards of Excellence

SP1
Obtain, evaluate, and communicate information about the relationship between distance, displacement, speed, velocity, and acceleration as functions of time.
a
Plan and carry out an investigation of one-dimensional motion to calculate average and instantaneous speed and velocity. • Analyze one-dimensional problems involving changes of direction, using algebraic signs to represent vector direction. • Apply one-dimensional kinematic equations to situations with no acceleration, and positive, or negative constant acceleration.
b
Analyze and interpret data using created or obtained motion graphs to illustrate the relationships among position, velocity, and acceleration, as functions of time.
c
Ask questions to compare and contrast scalar and vector quantities.
