## What is the linear speed of a point on the equator due to the Earth’s rotation Express your answer with the appropriate units?

At the equator, linear speed with respect to the polar (day/night spin ) axis is 463.82 meter/s = 1521.8 feet/s, At latitude 15oNand15oS , this speed is 447.77 meter/s = 1469.1 feet/s.

## What is the speed of a point on the equator physics?

The linear speed on a point at the equator on the surface of the Earth is going to be the radius of the Earth multiplied by this angular speed. So that’s 6.4 times 10 to the 6 meters—radius— times 2π radians over 86400 seconds which is 470 meters per second.

## What is the speed of someone on the equator?

Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.

## What is the linear velocity?

We define the rate of change in position over a time period as velocity. Linear velocity is simply an object’s velocity in a straight line, whereas Angular Velocity is how much an object spins, rotates, or turns.

3800​ m/s.

## What is the equation for linear speed?

We can use calculus to prove the formula for Linear Speed, which is v=rω. Consider a body moving with a uniform velocity v in a circular path of radius r.

## How do you find linear velocity?

The linear velocity v of the point P is the distance it traveled divided by the time elapsed. That is, v=st.

## What is the angular velocity of a point at the equator of the earth?

Based on the sidereal day, Earth’s true angular velocity, ωEarth, is equal to 15.04108°/mean solar hour (360°/23 hours 56 minutes 4 seconds). ωEarth can also be expressed in radians/second (rad/s) using the relationship ωEarth = 2*π /T, where T is Earth’s sidereal period (23 hours 56 minutes 4 seconds).

## What is the Earth’s angular speed the Earth’s radius is 6.37 106m it rotates once every 24 hours?

v1 = 463.1 m/s

– The speed of the point where θ = 18° from the equator v2 can be determined from the linear and rotational motion kinematic relation.

## What is the angular velocity of the Earth’s orbit around the sun?

(a) The angular speed of the earth in its orbit about the sun is ω = 2π/year = 2π/(365*24*60*60 s) = 2*107/s.

## How do you calculate the speed of the Earth at the equator?

If you estimate that a day is 24 hours long, you divide the circumference by the length of the day. This produces a speed at the equator of about 1,037 mph (1,670 km/h). You won’t be moving quite as fast at other latitudes, however.

## What is the latitude of any point on Earth’s equator?

latitude, angular distance of any point on the surface of the earth north or south of the equator. The equator is latitude 0°, and the North Pole and South Pole are latitudes 90°N and 90°S, respectively.

## Where is the speed of rotation of the Earth highest?

the Equator
The speed of rotation is greatest at the Equator and gets smaller with increasing latitude. For example, at Columbus (Latitude 40-degrees North): Circumference of the Earth at 40-deg North = 30,600 kilometers. Time to complete one Rotation = 24 hours.

## Is linear velocity speed?

Linear velocity is speed in a straight line (measured in m/s) while angular velocity is the change in angle over time (measured in rad/s, which can be converted into degrees as well).

## How do you find the linear velocity of a rotating object?

The Formula for Linear Speed
1. s = \frac {d}{t} Where, …
2. linear speed = angular speed \times radius of the rotation.
3. i.e. v = \omega \times r. v = linear speed (m per s)

6. \omega = 10.0 rev/s.
7. r = \frac{4}{2} = 2 m. …
8. v = \omega \times r,

## What is example of linear velocity?

Linear velocity is defined as distance over a period of time. For instance if a person ran 1 mile or approximately 1600 meters in 7 minutes, the they would have covered about 230 meters per minute.

## How do you find the linear speed of a point on the Earth?

The linear velocity is expressed in terms of the angular velocity of the earth’s rotation and the radius of the horizontal circle. Formulas used: -The linear velocity of a rotating body is given by, $v = r\omega$ where $r$ is the radius of the circle and $\omega$ is the body’s angular velocity.

720 m/s.

## What is the variable for linear speed?

At a distance r from the center of the rotation, a point on the object has a linear speed equal to the angular speed multiplied by the distance r. The units of linear speed are meters per second, m/s.

## What is the linear speed of a point on the rim of the disk?

answer: 31.4 rad/s (correct) Part B: What is the linear speed of a point on the rim of the disk? answer: 1.40 m/s (correct) Part C: Does a point near the center of the disk have.

## How do you find linear speed with radius and time?

Linear Speed

If the angle were not exactly 1 radian, then the distance traveled by the point on the circle is the length of the arc s=rθ, or the radius length times the measure of the angle in radians. Substituting into the formula for linear speed gives v=rθt or v=r⋅θt.

## What is the initial linear velocity?

v = initial linear velocity (m/s, ft/s) a = acceleration (m/s2, ft/s2) Linear distance can be expressed as (if acceleration is constant): s = v t + 1/2 a t2 (1c) Combining 1b and 1c to express the final velocity.

v =ω ×r.

## What is the angular speed of someone standing on the equator?

Earth angular speed is 7.27×105 rad /s

Earth angular speed is 7.2921159 x 105 rad/s from: World Book Encyclopedia Vol 6.

## How do you calculate angular velocity?

We can rewrite this expression to obtain the equation of angular velocity: ω = r × v / |r|² , where all of these variables are vectors, and |r| denotes the absolute value of the radius. Actually, the angular velocity is a pseudovector, the direction of which is perpendicular to the plane of the rotational movement.

When calculating the angular velocity of the Earth as it completes a full rotation on its own axis (a solar day), this equation is represented as: ωavg = 2πrad/1day (86400 seconds), which works out to a moderate angular velocity of 7.2921159 × 105 radians/second.

## Which factor does the torque on an object not depend on?

Which factor does the torque on an object not depend on? The angular velocity of the object to change.

## What is the angular speed and linear speed of Earth around sun?

We know the Earth goes round the Sun, all the way around is 2 radians (360 degrees). We also know that it takes a year (approx 365 days) which is therefore about 3.2×107 secs. Therefore = 2 / 3.2×107 = 2.0×107 rad/s.

## What is the angular speed of the Earth as it spins around its axis?

It takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of 7.2921159 × 105 radians/second.

## Which way does angular velocity point for Earth?

The angular velocity is positive since the satellite travels eastward with the Earth’s rotation (counter-clockwise from above the north pole.)
