What is the escape velocity of the Sun in miles per hour?
The escape velocity of our sun is nearly 1.4 million mph(1,381,755.55 mph), about 55 times greater than Earth's.
Is the greater an objects velocity the stronger the gravitational force on it?
No, the strength of the gravitational force on an object depends on the masses of the objects and the distance between them, not the object's velocity. The velocity affects the object's motion in the gravitational field, but not the strength of the gravitational force acting on it.
How are the satellites able to float in mid air?
they do not float. They are spinning with a certain velocity. First of all the satellites when launched are propelled through air at a speed equal or greater than its escape velocity.They then have a certain linear velocity but are able to maintain a lunar synchronous orbit because of the earth's gravity.
How often does shooting stars occur?
Shooting stars, also known as meteors, occur frequently but may not always be visible due to factors like weather and light pollution. During meteor showers, which happen multiple times throughout the year, you may have a better chance of seeing more shooting stars in a single night.
Do Jovian planets rotate faster than Terrestrial planets?
Yes, Jovian planets rotate faster than terrestrial planets. For example, Jupiter completes a rotation in about 10 hours, while Earth takes roughly 24 hours. This difference is mainly due to the Jovian planets having a greater amount of mass and their composition, which affects their rotation speeds.
What is tangential speed?
Linear speed is the distance traveled per unit of time, while tangential speed (or tangential velocity) is the linear speed of something moving along a circular path.[5] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Traveling a greater distance in the same time means a greater speed, and so linear speed is greater on the outer edge of a rotating object than it is closer to the axis. This speed along a circular path is known as tangential speed because the direction of motion is tangentto the circumference of the circle. For circular motion, the terms linear speed and tangential speed are used interchangeably, and both use units of m/s, km/h, and others.Rotational speed (or angular speed) involves the number of revolutions per unit of time. All parts of a rigid merry-go-round or turntable turn about the axis of rotation in the same amount of time. Thus, all parts share the same rate of rotation, or the same number of rotations or revolutions per unit of time. It is common to express rotational rates in revolutions per minute (RPM) or in terms of the number of "radians" turned in a unit of time. There are little more than 6 radians in a full rotation (2π radians exactly). When a direction is assigned to rotational speed, it is known as rotational velocity or angular velocity. Rotational velocity is a vector whose magnitude is the rotational speed.Tangential speed and rotational speed are related: the greater the RPM's, the larger the speed in meters per second. Tangential speed is directly proportional to rotational speed at any fixed distance from the axis of rotation.[6] However, tangential speed, unlike rotational speed, depends on radial distance (the distance from the axis). For a platform rotating with a fixed rotational speed, the tangential speed in the center is zero. Towards the edge of the platform the tangential speed increases proportional to the distance from the axis.[7] In equation form:where v is tangential speed and ω (Greek letter omega) is rotational speed. One moves faster if the rate of rotation increases (a larger value for ω), and one also moves faster if movement farther from the axis occurs (a larger value for r). Move twice as far from the rotational axis at the center and you move twice as fast. Move out three times as far and you have three times as much tangential speed. In any kind of rotating system, tangential speed depends on how far you are from the axis of rotation.When proper units are used for tangential speed v, rotational speed ω, and radial distance r, the direct proportion of v to both r and ω becomes the exact equationThus, tangential speed will be directly proportional to rwhen all parts of a system simultaneously have the same ω, as for a wheel, disk, or rigid wand. (The direct proportionality of vto r is not valid for planets, because planets have different rotational speeds).
Is a velocity of -7 greater or a velocity of -3 greater?
-4
A tappered cup rolled on a flat surface makes a circular path What does this tell you about the tangential speed of the rim of the wide end of the cup compared with that of the rim of the narrow end?
The tangential speed of the rim of the wide end of the cup is greater than that of the narrow end because the circular path covered by the wide end is larger than that covered by the narrow end. The rim of the wide end has to cover a greater distance in the same amount of time, hence its tangential speed is higher.
What would happen if the projectile were thrown with greater velocity?
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.
What would happen if a projectile were thrown with greater velocity?
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.
If two roller coasters have the same mass the one with the greater what will have a greater Kinetic energy?
The one with the greater velocity will have the greater kinetic energy.
How does the tapered rim of the wheel on a railroad train allow one part of the rim to have a greater tangential speed than another part when it is rolling on a track?
Tangential speed, unlike rotational speed, depends on radial distance. At the very center of the rotating platform, you have no speed at all; you merely rotate. But, as you approach the edge of the platform, you find yourself moving faster and faster. Tangential speed is directly proportional to distance from the axis for any given rotational speed.

What is the relation between stiffness and angular velocity?
The stiffness of a system affects how it resists deformation when a force is applied. As angular velocity increases, the deformation of a system may change due to the increased speed at which the system is rotating. In some cases, an increase in angular velocity may lead to a decrease in stiffness as the system experiences greater deformation.
What would happen if the projectile were thrown with a greater velocity?
If the projectile is thrown with a greater velocity, it would travel further and potentially reach a higher peak height. The increased velocity would also result in a shorter flight time and the projectile hitting the ground with a greater impact force.
Is distance directly proportional to velocity?
Distance Traveled is directly proportional to velocity. This is because velocity is the change in position over a period of time. The greater the velocity, the greater the distance traveled. For you calculus junkies, integrate velocity to get displacement.
If two vehicles are traveling at the same velocity which one has the greater momentum?
The vehicle with the greater mass will have the greater momentum, as momentum is dependent on both velocity and mass.
What happens to the terminal velocity if the weight is greater?
Other things (the volume and shape) being equal, a greater weight would cause a greater terminal velocity.
