aa\frac{\text{м}}{\text{с}^2}metre per second squared
KEY CONNECTIONS
Formulas
a=\frac{\left|v-v_0\right|}{t}a = |v − v₀| / t
a_{\text{ц}}=\frac{v^2}{R}=\omega^2Raц = v² / R = ω²R
v=v_0\pm atv = v₀ ± at
S=v_0t\pm\frac{at^2}{2}S = v₀t ± at²/2
S=\frac{v^2-v_0^2}{\pm 2a}S = (v² − v₀²) / (±2a)
NOTATION
Quantities in formulas
- a
- Acceleration is the rate of change of a body's velocity.

- Initial speed - the speed of the body at the selected initial moment.
- t
- Time is a quantity characterizing the duration and sequence of events.
- a_{\text{ц}}
- Centripetal acceleration is acceleration directed towards the center of curvature of the trajectory.
- R
- Radius is the distance from the center of the circle to its point.
- \omega
- Angular velocity is the speed of rotation of a body around an axis.
- S
