Atlanta Motorsports Park

We visit the birthplace of NASCAR, along with a brand new country club for car lovers. That’s right—instead of a golf course, they have a racetrack! In addition to looking back at the area's rich NASCAR history, Teachable Moments include an investigation of Newton's Second Law of Motion and an explanation of sound basics, including how sound waves dissipate over distance.

Science

S4P2

Obtain, evaluate, and communicate information about how sound is produced and changed and how sound and/or light can be used to communicate.

S4P3.c

Ask questions to identify and explain the uses of simple machines (lever, pulley, wedge, inclined plane, wheel and axle, and screw) and how forces are changed when simple machines are used to complete tasks.

S8P3.a

Analyze and interpret data to identify patterns in the relationships between speed and distance, and velocity and acceleration.

S8P3.b

Construct an explanation using Newton's Laws of Motion to describe the effects of balanced and unbalanced forces on the motion of an object.

S8P3.c

Construct an argument from evidence to support the claim that the amount of force needed to accelerate an object is proportional to its mass (inertia).

S8P4

Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.

S8P5.c

Plan and carry out investigations to identify the factors (e.g., distance between objects, magnetic force produced by an electromagnet with varying number of wire turns, varying number or size of dry cells, and varying size of iron core) that affect the strength of electric and magnetic forces.

SP1.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.
SP2.a

Construct an explanation based on evidence using Newton's Laws of how forces affect the acceleration of a body.

  • Explain and predict the motion of a body in absence of a force and when forces are applied using Newton's 1st Law (principle of inertia).
  • Calculate the acceleration for an object using Newton's 2nd Law, including situations where multiple forces act together.
  • Identify the pair of equal and opposite forces between two interacting bodies and relate their magnitudes and directions using Newton's 3rd Law.
SP4.c

Construct an argument that analyzes the production and characteristics of sounds waves.

SPS7.a

Construct explanations for energy transformations within a system.

SPS8.a

Plan and carry out an investigation to analyze the motion of an object using mathematical and graphical models.

SPS8.b

Construct an explanation based on experimental evidence to support the claims presented in Newton's three laws of motion.

SPS9.d

Analyze and interpret data to explain how different media affect the speed of sound and light waves.

1. How does knowledge of Newton's 2nd Law of Motion help race car drivers?

2. How difficult do you think it is to balance the desire to build an economy around racing with Dawsonville's desire for noise reduction? Why?

3. How can a knowledge of sound dissipation help event planners and entertainment professionals?
