AP Physics 1 Equations on Your TI-84 Plus CE (Notes Pack)

How it works The button opens this sheet in the CiNotes notes editor, ready to change. It’s 515 words, so it’s a one-time $3 (typed notes are free up to 300 words). You get a ZIP by email to send to your calculator. Works on the TI-84 Plus CE and CE Python. On OS 5.5 or newer, do the free one-time setup first.

AP Physics 1 equation sheet

Covers all eight units of the current AP Physics 1 course, including fluids. Checked against the College Board’s AP Physics 1 equation sheet, with a few extra relationships students use a lot (like v = √(2gh) for a hole in a tank).

Constants and units

Gravity near Earth	g = 9.8 m/s²
Universal gravitation	G = 6.67 × 10⁻¹¹ N·m²/kg²
Atmospheric pressure	1 atm = 1.0 × 10⁵ Pa
Units	N = kg·m/s²; J = N·m; W = J/s; Pa = N/m²

Kinematics

Velocity	v = v₀ + at
Position	x = x₀ + v₀t + ½at²
No time	v² = v₀² + 2a(x − x₀)
Graphs	slope of x–t is v; slope of v–t is a; area under v–t is displacement
Projectiles	v_x constant; a_y = −g; v_0x = v₀cos θ; v_0y = v₀sin θ

Forces

Newton’s second law	a_sys = ΣF/m_sys
Weight	F_g = mg
Friction	static F_f ≤ μ_sF_N; kinetic F_f = μ_kF_N
Spring	F_s = −kΔx
Gravitation	F_g = Gm₁m₂/r²; g = GM/r²
Incline at angle θ	along the slope mg sin θ; into the slope mg cos θ

Circular motion

Centripetal acceleration	a_c = v²/r, toward the center
Speed and period	v = 2πr/T

Energy and power

Kinetic energy	K = ½mv²
Work	W = Fd cos θ; ΔK = W_net
Spring energy	U_s = ½k(Δx)²
Gravitational energy	ΔU_g = mgΔy near Earth; U_G = −Gm₁m₂/r
Power	P_avg = W/Δt = ΔE/Δt; P = Fv cos θ
Conservation	if only gravity and springs do work, K + U stays the same

Momentum

Momentum	p = mv
Impulse	J = F_avgΔt = Δp; area under F–t graph
Center of mass	x_cm = Σmx/Σm; v_cm = Σmv/Σm
Collisions	no net outside force: total p conserved; elastic: K also conserved; perfectly inelastic: objects stick

Rotation

Rotational kinematics	ω = ω₀ + αt; θ = θ₀ + ω₀t + ½αt²; ω² = ω₀² + 2α(θ − θ₀)
Linking linear and angular	v = rω; a_T = rα
Torque	τ = rF sin θ; α = Στ/I
Rotational inertia	I = Σmr²; parallel axis I = I_cm + Md²
Rotational energy	K = ½Iω²
Angular momentum	L = Iω; point mass L = rmv sin θ; ΔL = τΔt
Rolling without slipping	v_cm = rω
Equilibrium	net force = 0 and net torque = 0

Oscillations

Period and frequency	T = 1/f
Mass on a spring	T = 2π√(m/k)
Pendulum (small angle)	T = 2π√(L/g)
Position	x = A cos(2πft) or x = A sin(2πft)

Fluids

Density and pressure	ρ = m/V; P = F_⊥/A
Pressure at depth	P = P₀ + ρgh; gauge pressure ρgh
Buoyant force	F_b = ρVg (fluid’s density, volume of fluid pushed aside)
Continuity	A₁v₁ = A₂v₂
Bernoulli	P₁ + ρgy₁ + ½ρv₁² = P₂ + ρgy₂ + ½ρv₂²
Hole in a tank at depth h	v = √(2gh)
Water	ρ = 1000 kg/m³

What it looks like on the calculator

The calculator version is the same sheet in plain text with short lines, so it fits the screen. Square roots are written as sqrt( ), powers with ^ and Greek letters as words. On the calculator, search a word like “torque” or “Bernoulli” to jump straight to it. The notes are stored in Archive, so a RAM clear won’t erase them.

Want your own class notes on there too?

Upload your teacher’s study guide or review packet as a PDF ($3 for up to 10 pages), or paste in your own notes. Diagrams come through as pictures.

Common questions

How much does it cost to put this on my calculator?

This sheet is 515 words, so it’s a one-time $3. Typed notes are free up to 300 words and $3 from 301 to 10,000 words. If you cut it down to 300 words or fewer, it’s free. You can also add your own notes to the same order, up to 10,000 words in total (about 9,485 more words).

Does this work for regular or honors physics too?

Mostly, yes. Kinematics, forces, energy, momentum and circular motion are the same equations in any algebra-based physics class. Rotation and fluids may be more than your class needs, and you can delete those parts in the editor.

Can I change the notes before I pay?

Yes. The button opens the sheet in the CiNotes notes editor. Delete what you don’t need, add your teacher’s examples, and check the calculator preview before you check out.

Will it work on my calculator?

It works on the TI-84 Plus CE and the TI-84 Plus CE Python. It doesn’t work on the TI-84 Evo or on black-and-white TI-84s. If your calculator is on OS 5.5 or newer, it needs a free one-time setup first. The setup guide walks you through it.

Will the notes disappear if my calculator resets?

No. The notes are stored in Archive, so a RAM clear won’t erase them. On OS 5.5 or newer, open AsmHook2 from the APPS menu once after a RAM clear, then open your notes as usual.
