Ok so tomorrow is my Physics final and I have so much depending on this one test ( all my other grades are 80 and above but this one is a low 70). I have studied for the final but if anyone could supply me with a list of most know formulas for physics I would really appreciate it. Thanks in advance!
I hope this helps!

Of course! I'd be happy to provide you with a list of important physics formulas to help you prepare for your final. However, it's important to note that simply memorizing formulas may not be enough. Understanding the concepts behind each formula and how to apply them is crucial for success in physics.
That being said, here are some key physics formulas that cover various topics:
1. Newton's Second Law of Motion:
- F = m * a (force equals mass times acceleration)
2. Gravitational Force:
- F = G * (m1 * m2) / r^2 (force between two masses)
3. Work-Energy Theorem:
- W = F * d * cosθ (work equals force times displacement times the cosine of the angle between them)
4. Kinetic Energy:
- KE = (1/2) * m * v^2 (kinetic energy equals half the mass times velocity squared)
5. Potential Energy:
- PE = m * g * h (potential energy equals mass times gravity times height)
6. Conservation of Energy:
- KE1 + PE1 = KE2 + PE2 (the total mechanical energy is conserved in a closed system)
7. Ohm's Law:
- V = I * R (voltage equals current times resistance)
8. Coulomb's Law:
- F = k * (|q1 * q2|) / r^2 (force between two charged objects)
9. Snell's Law:
- n1 * sin(θ1) = n2 * sin(θ2) (relating the angles of incidence and refraction in optics)
10. Hooke's Law:
- F = k * x (force equals spring constant times displacement)
Remember, this is just a small selection of important physics formulas. I would recommend reviewing your course materials, lecture notes, and textbooks for a more comprehensive list. Also, make sure to practice solving problems and applying these formulas to be well-prepared for your final exam.
Always try to understand the concepts behind the formulas, the units used, and their interrelationships. Good luck on your final!
