What is the equation of time period?
For determining the time period (T).
For Example: A lift moving upwards with acceleration ‘a’, then, T = 2π × (L/geff) = 2π √[L/(g + a)] If the lift is moving downward with acceleration ‘a’, then T = 2π × (L/geff), geff = √(g2 + a2) or, T = 2π × √[L/(g2 + a2)1/2].
What speed means?
Speed is a scalar quantity that refers to “how fast an object is moving.” Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
What is the formula for maximum speed?
Comparing this equation to v = vmax cos (ωt + φ), results in the value of maximum speed in SHM, simply vmax = Aω.
What is meant by a simple pendulum?
: an ideal pendulum consisting of a point mass suspended by a weightless inextensible perfectly flexible thread and free to vibrate without friction —distinguished from physical pendulum.
What is the formula of time in motion?
Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
Is velocity and speed the same?
The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.
How do we find speed?
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
What is the unit of speed?
The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.
What is dimensional formula?
Dimensional formula is an expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), length (L), and time (T). A dimensional formula is expressed in terms of powers of M,L and T.
What is period of oscillation?
The time to complete one oscillation remains constant and is called the period T. Its units are usually seconds, but may be any convenient unit of time.
What is the formula for finding time?
The precise definition of the Equation of Time is E = GHA (apparent Sun) – GHA (mean Sun) (1) where GHA is the Greenwich hour angle. An alternative formula often quoted in text books is E = right ascension of the fictitious mean Sun – right ascension of the apparent (actual) Sun.
