What keeps mars in orbit around the sun?
The Sun's gravity combined with the tangential ("sideways") velocity of Mars.
Where on the surface of the earth should you stand to experience the least centripetal acceleration?
Hello, To answer the question, the place where one would experience the least amount of centripetal acceleration would be at either the north or south pole. If you think about it, the part of the Earth that the spins the fastest is at the Equator. The North and South poles move the least while the Earth spins. Centripetal Force is all about making sure that a object on a spinning sphere keeps going around in a circle. If the object spins at a greater rate, the centripetal acceleration would be larger because there is more of a "pull" to keep the object in line.
Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
What is the centripetal acceleration of the Earth in its orbit around the Sun?
The centripetal acceleration of the Earth in its orbit around the Sun is approximately 0.0059 m/s². It is directed towards the center of the Sun and keeps the Earth moving in its circular path. This acceleration is necessary to counterbalance the gravitational force between the Earth and the Sun.
What two motion form an orbit?
An orbit is formed when an object is moving in a curved path around another object due to the gravitational pull between them. The two motions involved in an orbit are the object's forward motion (tangential velocity) and the pull of gravity keeping it in a curved path (centripetal force).
Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
Is it possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration?
Yes, it is possible to have positive instantaneous tangential velocity and negative instantaneous tangential acceleration. This occurs when an object is moving in the positive direction but slowing down due to a decrease in its speed.
How is tangental velocity related to the moon falling around the earth?
Tangential velocity is the velocity at which an object moves along a curved path. In the case of the moon orbiting the Earth, the tangential velocity of the moon allows it to stay in its orbit and not fall into the Earth due to the balance between the gravitational force pulling it towards Earth and the centripetal force keeping it in orbit.
How can one determine the tangential velocity of an object in motion?
To determine the tangential velocity of an object in motion, you can use the formula: tangential velocity radius x angular velocity. The tangential velocity is the speed at which an object moves along its circular path. The radius is the distance from the center of the circle to the object, and the angular velocity is the rate at which the object rotates around the center. By multiplying the radius and angular velocity, you can calculate the tangential velocity of the object.
What is the relationship between tangential velocity and circular motion?
In circular motion, tangential velocity is the speed at which an object moves along the circumference of the circle. It is perpendicular to the radius of the circle at any given point. The relationship between tangential velocity and circular motion is that the tangential velocity determines how fast an object is moving around the circle, while the radius of the circle affects the magnitude of the tangential velocity.
Why does centripetal acceleration occur?
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
Is angular velocity the same as tangential velocity?
No. If you can drive around a ten-mile track in the same time it takes you to drive around a one-mile track, then your angular velocity is the same in both cases. But in order to do that, you'll need much higher tangential velocity during the longer run. Tangential velocity is what you'd normally call your 'speed' as you blaze around the track.
How do you find tangential velocity?
Tangential velocity can be found by multiplying the angular velocity (in radians per second) by the distance from the axis of rotation to the point of interest. It represents the speed at which an object is moving around a circle or rotating about a point.
What two types of motions keep a satallite in orbit around earth?
A tangential velocity vector relative to the orbit itself, and acceleration towards the center of the planet due to gravity.
What are examples of centipetal acceleration?
Examples of centripetal acceleration include a car moving around a curve, a spinning top, or a satellite orbiting around Earth. These objects experience centripetal acceleration because their velocity is constantly changing direction towards the center of the circular path they follow.
How does the tangential velocity of a planet relate to it orbiting around the sun?
The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.
What is the centripetal acceleration of mercury?
The centripetal acceleration of Mercury due to its orbit around the Sun is approximately 0.377 m/s^2. This acceleration is directed towards the center of the Sun and is responsible for keeping Mercury in its orbital path. It is calculated using the formula a = v^2/r, where v is the orbital velocity of Mercury and r is its average distance from the Sun.
