Summary of physics formula in grade one of senior high school 1. Motion of particle (1) linear motion (1) uniform velocity linear motion (1). Average velocity V flat = s / T (definition) 2. Useful inference VT ^ 2 – VO ^ 2 = 2As 3. Velocity V T / 2 = V flat = (VT + VO) / 2 4. Final velocity V T = VO + at 5. Velocity V S / 2 = [(VO ^ 2 + VT ^ 2) / 2] 1 / 2 6. Displacement S = V flat t = VO + at ^ 2 / 2 = VT / 2T 7. Acceleration a = (VT VO) / t takes VO as positive direction, When a is in the same direction (acceleration) as VO, a > 0; when a is in the opposite direction, a > 0
