Free TI-84 Physics Mechanics Help: 3 Calculator Programs

Martin McSweeney

Physics Mechanics Help, Right on Your TI-84

Three free programs for reviewing motion, forces, energy, momentum, oscillations, fluids, and rotation.

Knowing a physics formula is one thing. Knowing when to use it can be the harder part. This free Physics Mechanics Concept Help Pack puts explanations, equations, worked examples, and common-mistake guidance on your calculator so you can review the ideas behind a problem.

What These Programs Do

These are concept-help and reference programs. You choose a topic and read its explanations, formulas, and examples. The displayed examples use preset numbers; the free programs do not accept your problem's values and calculate a new answer. References to MECH1, MECH2, and CIRMOT point to separate solver programs in the Physics Mechanics bundle.

Which Program Should You Open?

Program Topics to Review
MEC1HELP Kinematics, projectile motion, Newton's laws, forces and free-body diagram setup, friction, connected systems, work and energy, power, momentum, collisions, and gravitation.
MEC2HELP Springs, simple harmonic motion, pendulums, orbital motion, escape velocity, Kepler's third law, density, pressure, buoyancy, continuity, Bernoulli's equation, and Torricelli's law.
CIRHELP Centripetal force, vertical circles, banked roads, flat-curve friction, tabletop-hanger systems, conical pendulums, rotational kinematics, torque, moment of inertia, angular momentum, and rolling motion.

Use the Help Pack to Plan Your Approach

Start with the topic that matches your homework. Read the explanation, identify the quantities involved, and compare the worked example with your own problem. Look for reminders about signs, units, assumptions, and common mistakes before doing your calculation.

  • Choosing a motion equation? Open MEC1HELP for constant-acceleration equations, sign conventions, and guidance on matching an equation to your known and unknown quantities.
  • Working with springs or pendulums? Open MEC2HELP to review period, frequency, energy, amplitude, and the small-angle approximation for pendulums.
  • Studying a turn, loop, or rotating object? Open CIRHELP to review inward forces, vertical-circle setups, torque, and connections between linear and rotational motion.

Three Examples to Try First

1. A Car Accelerating from Rest

Open: MEC1HELP → Kinematics → Worked Example.

Follow a car accelerating at 3.0 m/s² for 6.0 seconds. The example finds a final velocity of 18 m/s and a displacement of 54 m, then checks the result with another kinematics equation.

2. A Mass Oscillating on a Spring

Open: MEC2HELP → Springs and SHM → More → Worked Example.

Review a 0.4 kg mass on a spring with k = 160 N/m and an amplitude of 0.15 m. The example shows a period of about 0.314 s, a frequency of 3.18 Hz, total energy of 1.8 J, and a maximum speed of 3.0 m/s.

3. Finding the Required Inward Force

Open: CIRHELP → Centripetal Force. Advance through the explanation to the example.

A 2 kg object moving at 4 m/s in a circle of radius 0.5 m needs a net inward force of 64 N. The explanation also clarifies that centripetal force is supplied by existing forces such as tension, gravity, or friction.

How to Install and Open the Programs

  1. Download the three .8xp files using the buttons above.
  2. Connect your calculator to your computer with a USB cable.
  3. Transfer the files using TI Connect CE. Follow the TI-84 Plus CE installation guide for instructions.
  4. On the calculator, press [PRGM], select MEC1HELP, MEC2HELP, or CIRHELP, and press [ENTER] to paste the program command. Press [ENTER] again to run it.
  5. Choose a topic from the menu. Press [ENTER] at each pause to continue reading.

Calculator Models

For the TI-84 Plus CE, TI-84 Plus CE Python, TI-84 Plus CE-T, and TI-84 Plus CE-T Python. These are TI-BASIC programs transferred as .8xp files, including on Python-edition calculators.

Common Questions

Do I need the paid bundle to use these programs?

No. Each free help program opens independently. You can read the explanations and preset examples without installing the separate solver programs mentioned in the help text.

Will these programs solve my own physics problems?

The free pack provides reference material and worked examples. To calculate answers for your own values, use your calculator's normal calculations or a separate solver program.

Do I need an internet connection while using them?

Once the files are transferred, the help text is stored on your calculator and can be read offline.

Explore the Physics Mechanics Bundle
