Question: what are the basic formulas in physics?
Answer: s=d/t. Speed = distance / time. ... 
v=d/t. Velocity= displacement / time . ... 
a=(vf-vi)/t or Δv/t. Acceleration is equal to (final v - initial v) / time. ... 
g=10 m/s² Gravity; acceleration of a free falling object is 10 m/s². ... 
F=ma. ... 
Fg=mg=W. ... 
F=kx. ... 
Ek=1/2mv²
