KEY CONNECTIONS
Formulas
t=\frac{S}{v}t = S / v
t=\frac{\left|v-v_0\right|}{a}t = |v − v₀| / a
t=\sqrt{\frac{2h}{g}}t = √(2h / g)
t=\sqrt{\frac{2S}{a}}t = √(2S / a)
t=\frac{m}{kI}t = m / (kI)
\tau=\frac{\tau_0}{\sqrt{1-\frac{v^2}{c^2}}}τ = τ₀ / √(1 − v²/c²)
NOTATION
Quantities in formulas
- t
- Time is a quantity characterizing the duration and sequence of events.
- S
- Distance - the length of the space between selected points.
- v
- Velocity is the rate and direction of change of a body's position.
- v_0
- Initial speed - the speed of the body at the selected initial moment.
- a
- Acceleration is the rate of change of a body's velocity.
- h
- Height - vertical distance from the selected level.
- g
- Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
- m
- Mass is a scalar physical quantity that is a measure of the inertia of a body.
- k
- Electrochemical equivalent is the mass of a substance released by a unit charge.
- I
- Current strength is the charge passing through the cross section of a conductor per unit time.
- \tau_0
- Proper time is time measured in the reference system associated with the object.
- c
- The speed of light in a vacuum is the maximum speed of propagation of interactions.
