v = S / t
vav = S/t
v = v₀ ± at
v = v₀ + gt
v = √(2gh)
vkv = √(3RT / M)
v = 2πR / T = 2πRν = ωR
ac = v² / R
v = λν
c = λν
NOTATION
Quantities in formulas
- Speed is the speed and direction of change in body position.
- Distance - the length of the space between selected points.
- Time is a quantity characterizing the duration and sequence of events.
- Average speed is the ratio of the distance traveled to the time of movement.
- Initial speed - the speed of the body at the selected initial moment.
- Acceleration is the rate of change in the speed of a body.
- Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
- Height - vertical distance from the selected level.
- Root mean square velocity is a characteristic of the thermal motion of gas particles.
- The universal gas constant is the coefficient of connection between the parameters of an ideal gas.
- Temperature is a measure of the thermal state of the body.
- Molar mass is the mass of one mole of a substance.
- Radius is the distance from the center of the circle to its point.
- A period is the time of one complete repetition of a process.
- Frequency is the number of repetitions of a process per unit of time.
- Angular velocity is the speed of rotation of a body around an axis.
- Centripetal acceleration is acceleration directed towards the center of curvature of the trajectory.
- Wavelength is the distance between the nearest points of a wave in the same phase.
- The speed of light in a vacuum is the maximum speed of propagation of interactions.
