Is the linear speed of a child sitting near the center of a rotating merry-go-round the same as that of another child sitting near the edge of the same merry-go-round explain?
Is the linear speed of a child sitting near the center of a rotating merry-go-round the same as that of another child sitting near the edge of the same merry-go-round? No, the child near the edge has a larger linear velocity because her radius is larger while her rotational displacement is the same as the other child.
What is linear speed?
Linear speed is measured in distance units per unit time (e.g. feet per second). The word linear is used because straightening out the arc traveled by the object along the circle results in a line of the same length, so that the usual definition of speed as distance over time can be used.
What is the relationship of linear speed to rotational 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.

Which horse moves faster in m/s on a merry-go-round?
Jamarcus Gislason posed the question. 4.2 out of 5 stars (72 votes) It takes exactly the same amount of time for each horse to travel through a complete circle. The horses on the outside of the carousel must go a greater distance in the same period of time as the horses on the interior of the carousel. Therefore, horses on the outside have a quicker linear speed than horses at their respective centers.
Is a merry-go-round faster on the outside?
No, you are moving more quickly. As it rotates, it has uniform circular motion, which implies that it rotates at a consistent angular speed throughout its rotation. Because you are circling with uniform circular motion, the value of w is the same for each of you, which means that the closer you are to the center, the slower your linear speed becomes.
Which animal has a quicker stride?
Cheetah is the fastest terrestrial animal on the planet. Due to the length and flexibility of their spines, cheetahs are able to cover great distances with each step, and they alter the number of steps they take per second as they accelerate, taking more steps per second as they run faster. Cheetahs can cover 23 feet in a single stride and can perform four steps per second while running at peak speed.
Which has the greater tangential and rotational speed on a merry-go-round the person near the outer rail or the one closer to the inner rail?

Why do you fall off a merry go round?
Generally speaking, the wider the circle in which you move, the higher the centripetal force you will experience, and vice versa. Consequently, the farther you are from the center of a merry-go–round, the more power the merry-go-round must use on you in order to keep you traveling in that circle.
Does a merry go round have torque?
What is the source of the lack of torque on the merry go round? There is no torque since you have just stepped off the pedal. If you had jumped off, it may have made a difference – unless you had leapt off in a radial direction, in which case it would not have made a difference (this also would exert no torque). When there is no torque, there is no CHANGE in angular momentum.

Where does a ladybug sitting on a rotating record?
The highest linear speed of a ladybug resting on a revolving record is found on the outside or outside rim of the record, which is the outer edge of the record. The ladybug’s reasonable speed remains constant regardless of where the ladybug appears on the track record. It is possible that she may have no linear speed, but she will have rotating speed.
Which has greater linear speed a horse near the outside real of a merry-go-round or a horse near the inside real?
In a merry-go-round, which horse is closer to the outer rail and which horse is closer to the inner rail has faster linear speed? The horse on the outside. Angular speed is determined by the location of the horse on the merry-go-round. A horse near the outer rail has a larger angular speed than a horse near the inner rail. Neither of them—they both have the same angular velocity.
What happens when you spin a Merry Go Round?
In a merry-go-round, which horse is closer to the outer rail or which horse is closer to the inner rail has faster linear speed? It’s a horse from outside. Angular speed is determined by the location of the horse on the merry-go-round. Is it faster for a horse near the outer rail or faster for a horse near the interior rail? There is no difference between the two because they both have the same angular speed.
Why does the outside of a circle move faster than the inside?
I know it sounds strange, but while riding a merry-go-round, it occurred to me that the circumference of a circle is larger on the outside than it is on the inside. Therefore, the edge of the merry-go-round would have to be moving faster than the center of the merry-go-round because it has a greater distance to travel than the center.
Is the top of the wheel moving at the same speed as the car?

- It completes one complete rotation around the sun every 365 14 days.
- 10.1 Rotation and Revolution of the Earth 67Uniform Circular Motion is a type of circular motion.
- In a circular path, the object moves at a constant (uniform) speed around the circumference, which equals the distance around the circle (C = 2r).
- rotational speed (in rpm) 10.2 The distance traveled in one unit of time is referred to as linear speed.
The larger the distance between the axis and the object, the greater the tangential speed.
The relationship between tangential speed and rotational speed is well established.
rotational speed = tangential velocity multiplied by the radial distance Vt = r * w = Vt = r * w rotational speed (in rpm) 10.2 10 It may be represented by the symbol, where v denotes tangential speed and r denotes rotating speed (pronounced oh MAY guh).
You will also travel more quickly if you are located further away from the axis (bigger r).
Identify v v = 3.77 m/s 1.2 m 1.2 m T=2s12Uniform Circular Motion is defined as Speed is constant; but, velocity is not constant; hence, velocity is always changing; this acceleration is referred to as “centripetal” acceleration.
The 14th centripetal acceleration (Centripetal Acceleration) Draw the two velocity vectors in such a way that their tails are the same length.
Draw the triangle formed by the change in position, and you will obtain the triangle in (b)15Centripetal Acceleration.
16 Centripetal Acceleration17 is a term used to describe the acceleration of a centripetal force.
A c = V 2 / r centripetal acceleration F c = m (v 2 / r) centripetal acceleration centripetal force is a force that rotates around a point.
20 Centripetal acceleration is defined as acceleration toward the center.

14.3 Elliptical Orbits per Minute 49 What is the shape of a satellite’s route as it travels around the Earth in an orbit?
Total energy is equal to the sum of kinetic energy and potential energy.
51 It is largest when the satellite is at apogee and least when the satellite is at perigee, according to the PE equation.
Throughout the orbit, the total of the KE and PE remains constant at every point in time.
This means that the speed, and hence the KE, cannot be changed.
