What causes synchronous rotation?
Synchronous rotation occurs when an object's rotation period matches its orbital period, usually due to tidal forces from a nearby gravitational body. This synchronization locks one face of the rotating body to always face the same direction as it orbits, resulting in consistent positioning. It is commonly observed in natural satellites like the Moon, as well as in planet-moon systems like Earth-Moon.
Why does the moon exhibit a much stronger tidal effect on Earth than does Jupiter?
This is because Jupiter is much farther away. This equation measures the Force (F) in Newtons that two objects have on each other. F=G (m1m2)/R R is distance. M1 is the mass of object 1, m2 is the mass of object 2, and G is the gravitational constant.
Why does earth feel a greater tidal force from the moon than from the sun?
The moon is closer to Earth, and, since gravitational force varies inversely with the distance and mass of two objects, since the sun is farther away, even though it has more mass, it has less pull on the earth.
Why does the Moon generate larger tidal forces than the Sun?
Even though the Sun is much more massive than the Moon, the Moon is much closer. The force of gravity between two objects is not only determined by the masses of those objects but the distance between them. Because the Moon is so much closer, the effects of its gravity on tidal forces is greater.
What are the causes by of gravity that produced gravitational force attraction of mass of celestial body?
Gravity is caused by the curvature of spacetime around massive objects. This curvature creates a gravitational force that attracts objects with mass towards each other. The more massive an object is, the stronger its gravitational force will be.
The space surrounding a massive object subject to the body's force of attraction is?
The space surrounding a massive object subject to the body's force of attraction is the gravitational field. This field is responsible for exerting a force on any other object within its influence, causing it to experience gravitational acceleration towards the massive object.
What fundamental force is responsible for tidal?
Gravitational force between Earth - Moon - Sun is the fundamental force behind the tidal motion.
Does the moon make the gravitational attraction of tides?
Technically, every other massive body in the universe causes tidal effects; as a practical matter, only very close or very massive objects have any real effect. So we see tidal effects on the Earth caused by the Moon, which is close, and to a lesser extent by the Sun - which is far more massive, but also much farther away. No other body is either close enough or massive enough to have any influence on the tides at all.
What is the definition of tidal bulge?
The gravitational pull of the Sun and the Moon cause the tidal bulges.
Do tidal waves cause damage?
Yes, tidal waves can cause significant damage along coastlines due to their massive size and powerful force. They can flood coastal areas, sweep away buildings and infrastructure, and result in loss of life and property damage. Preparedness and early warning systems are crucial in minimizing the impact of tidal waves.
A very massive object A and a less massive object B move toward each other under the influence of gravitation Which force if either is greater?
If gravity is moving the objects toward each other, a massive body (i.e. the earth) will be in the way. If the objects are at the same ditance from this body, a greater force is exerted on object A.
What causes synchronous rotation?
Synchronous rotation occurs when an object's rotation period matches its orbital period, usually due to tidal forces from a nearby gravitational body. This synchronization locks one face of the rotating body to always face the same direction as it orbits, resulting in consistent positioning. It is commonly observed in natural satellites like the Moon, as well as in planet-moon systems like Earth-Moon.
What is meant by acceleration due to gravity?
Earth being a massive body attracts every other massive body. This force of attraction is named as weight of the body. But force is equated to the expression m*a Here m is the mass of the body and a is the acceleration. So the general a is to be replaced by g a symbol meant for the acceleration due to gravity. Its average value is 9.8 m/s2
How can gravity change the motion of an object?
Gravity can change the motion of an object by pulling it towards a massive body, such as a planet or star. This force causes the object to accelerate towards the center of mass of the massive body, changing its speed and direction of motion. The greater the mass of the object or the closer it is to the massive body, the stronger the gravitational force and the greater the impact on the object's motion.
As the mass of a body increases its gravitational force of attraction on the earth?
increases as well, due to the greater mass of the body. This is because gravity is directly proportional to the mass of the object. So, the more massive the body, the stronger the gravitational force it exerts on Earth.
Is gravity considered an external force?
Yes, gravity is considered an external force because it acts on objects from outside of them, pulling them towards the center of the Earth or another massive body.
How does a tidal stream generator work?
Tidal Turbines work when the tide goes in and out. The force from the movement of the water spins the turbines.
