PHYSICAL QUANTITY

Acceleration: formulas and units of measurement

Acceleration: symbol a, unit m/s². Formulas and explanations for Mechanics.

ameters per second squared

KEY CONNECTIONS

Formulas

a = |v − v₀| / t

ac = v² / R = ω²R

v = v₀ ± at

S = v₀t ± at²/2

S = (v² − v₀²) / (±2a)

NOTATION

: Acceleration is the rate of change in the speed of a body.
: Speed is the speed and direction of change in body position.
: Initial speed - the speed of the body at the selected initial moment.
: Time is a quantity characterizing the duration and sequence of events.
: Centripetal acceleration is acceleration directed towards the center of curvature of the trajectory.
: Radius is the distance from the center of the circle to its point.
: Angular velocity is the speed of rotation of a body around an axis.
: Distance - the length of the space between selected points.
