How do you find the rotational period in physics?
How do you find the rotational period in physics?
Calculating Planetary-Rotation Periods The planetary-rotation period can even be calculated from the velocity-distance-time equation, T = D/V, where D = distance, in this case the circumference (2πR), and V = tangential velocity.
What is the formula of time period in projectile motion?
T tof = 2 ( v 0 sin θ 0 ) g . T tof = 2 ( v 0 sin θ 0 ) g . This is the time of flight for a projectile both launched and impacting on a flat horizontal surface.
What are the formulas equations of projectile motion?
The motion of such a particle is called Projectile Motion. In the above diagram, where a particle is projected at an angle θ, with an initial velocity u….Few Examples of Two – Dimensional Projectiles.
| Quantity | Value |
|---|---|
| Equation of path of projectile motion | y = (tan θ0)x – gx2/2(v0cosθ0)2 |
How do you calculate the rotational period of the sun?
To calculate the sidereal period from the synodic value, Let R = sidereal period S=synodic period Then R = S χ 365.26 (S + 365.26) The value of 365.26 is the number of days in an Earth Sidereal year. Solar astronomers have found that the Sun exhibits a differential rotation.
What do you mean by period of rotation?
the mean time taken for one body, such as a planet, to complete a revolution about another, such as the sun.
What is rotary motion in physics?
Rotational motion refers to anything spinning or moving in a circular path. It is also called angular motion or circular motion. The motion may be uniform (i.e., the velocity v doesn’t change) or non-uniform, but it has to be circular.
How do you calculate the rotation rate of a sunspot?
For each sunspot, the rotation is calculated by subtracting the initial longitude from the final longitude and dividing by the number of days between observations. This answer will be in degrees per day and is a measure of the rotation rate of the Sun. Rotation rate is 48/4 = 12 degrees per day.
Why is knowing the rotational period of the Sun significant?
Why is rotation period important? For one thing, it is believed that the solar rotation ultimately causes the creation of sunspots themselves. Other stars (with similar, or cooler, temperature) that rotate more rapidly than the Sun can have more and bigger spots.
