Formula Flashcards
1
Q
Velocity
A
Distance / time
2
Q
Acceleration
A
🔺velocity (Vf-Vi) / 🔺time (Tf-Ti)
3
Q
Uniformly accelerated rectilinear motion
A
- Vf = Vi + at
- Vf^2 = Vi^2 + 2ad
- D= 1/2 (vf + vi) t
- D= Vit + 1/2 at2
4
Q
Uniformly accelerated rectilinear motion due to gravity
A
- Vf = Vi - gt
- Vf^2 = Vi^2 - 2gd
- D= 1/2 (vf + vi) t
- D= Vit + 1/2 gt2
