As a student of physics, having a comprehensive formula sheet is essential for success. This sheet can serve as a quick reference guide, providing you with the necessary equations you need to solve problems and comprehend the concepts covered in your Physics I course. The formulas presented in this sheet are organized into different sections based on the topics commonly taught in introductory physics.
1. Kinematics
Kinematics is the study of motion without considering the forces that cause it. The following formulas are used to describe the motion of objects in one dimension:
Position:
$$ x = x_0 + v_0t + \frac{1}{2}at^2 $$
Velocity:
$$ v = v_0 + at $$
Acceleration:
$$ a = \frac{v-v_0}{t} $$
Displacement:
$$ \Delta x = x_f – x_i $$
Average Velocity:
$$ v_{avg} = \frac{x_f – x_i}{t_f – t_i} $$
2. Dynamics
Dynamics is the study of the relationship between forces and motion. The following formulas are used to solve problems involving forces, mass, and acceleration:
Newton’s Second Law:
$$ F = ma $$
Force of Gravity:
$$ F_g = mg $$
Centripetal Force:
$$ F_c = mv^2/r $$
Work:
$$ W = Fd $$
Power:
$$ P = Fv $$
Kinetic Energy:
$$ K = \frac{1}{2}mv^2 $$
Potential Energy:
$$ U = mgh $$
3. Circular Motion and Gravitation
Circular motion and gravitation are two important topics in physics that involve the study of objects moving in circular paths and the force that attracts objects with mass, respectively:
Period of a Circular Motion:
$$ T = 2\pi r / v $$
Frequency of a Circular Motion:
$$ f = 1/T $$
Gravitational Force:
$$ F_g = Gm_1m_2/r^2 $$
Gravitational Constant:
$$ G = 6.674 × 10^{-11} Nm²/kg² $$
4. Thermodynamics
Thermodynamics is the study of heat and its relationship to other forms of energy. The following formulas are used to solve problems involving temperature, heat, and work:
Ideal Gas Law:
$$ PV = nRT $$
Heat Capacity:
$$ C = Q / ΔT $$
Specific Heat:
$$ c = Q / (mΔT) $$
Latent Heat:
$$ L = Q / m $$
5. Waves
Waves are disturbances that propagate through a medium. The following formulas are used to describe the properties of waves:
Wave Velocity:
$$ v = fλ $$
Frequency:
$$ f = 1/T $$
Wavelength:
$$ λ = v/f $$
Amplitude:
$$ A = (ymax – ymin)/2 $$
6. Optics
Optics is the study of light and its interactions with matter. The following formulas are used to solve problems involving lenses, mirrors, and the properties of light:
Thin Lens Equation:
$$ 1/f = 1/d_o + 1/d_i $$
Mirror Equation:
$$ 1/f = 1/d_o + 1/d_i $$
Index of Refraction:
$$ n = c/v $$
Snell’s Law:
$$ n_1sinθ_1 = n_2sinθ_2 $$
