What is the relationship between gravity and acceleration?
Acceleration is the result of the second-second acceleration of 9.8, which is caused by the force of the earth's objects per kilogram being subjected to the force of 9.8 cattle, that is, the force of 9.8 cattle per kilogram of objects, then the object is moving forward in the direction of an acceleration force of 9.8 meters per second. therefore, the two quantities are defined in different directions.
The second of gravity acceleration is the g ---- 9.8N/kg on the earth.
If an object is subjected to a horizontal force of 5N to the right, its acceleration cannot be determined because it does not know its quality. For a dust, the acceleration will be very large, but for a large car, its speed needs to increase slowly-the acceleration is not large.
What is gravity acceleration? Which is it?
The acceleration of an object near the earth's surface due to gravity is called the acceleration of gravity, also known as the acceleration of free fall, expressed in g.
The direction of gravity acceleration g is always vertical and downward. At the same height in the same region, the gravity acceleration of any object is the same. The value of gravity acceleration decreases as the altitude increases. G does not change much when the height of an object is much smaller than the Earth's radius. When the distance from the ground is large, the g value of gravity acceleration is significantly reduced, so g cannot be considered as a constant.
The acceleration of gravity at the same distance increases with the increase of latitude. Since gravity is a force splitting of gravitation, another force splitting of gravitation provides the centripetal force required for the circular motion of an object around the Earth axis. The higher the latitude of the geographic location of the object, the smaller the orbital radius of the circular motion, and the smaller the centripetal force required, the larger the gravity and the greater the acceleration of gravity. The radius of the circular motion orbit at the north and south poles is 0, the centripetal force is also 0, and the gravity is equal to the gravitation. At this time, the gravity acceleration reaches the maximum.
As g does not change much with the latitude, the gravity acceleration g = 9.80665 Mbit/s ^ 2 of the object is measured accurately at the sea level at the latitude of 45 ° internationally. In solving the problem near the earth's surface, g is usually used as a constant. In general calculation, g = 9.80 m/s ^ 2 can be obtained. Both theoretical analysis and accurate experiments show that the value of gravity acceleration g increases with the increase of latitude. For example:
Equator g = 9.780 m/s ^ 2
Guangzhou g = 9.788 m/s ^ 2
Wuhan g = 9.794 m/s ^ 2
Shanghai g = 9.794 m/s ^ 2
Tokyo g = 9.798 m/s ^ 2
Beijing g = 9.801 m/s ^ 2
New York g = 9.803 m/s ^ 2
Moscow g = 9.816 m/s ^ 2
G = 9.832 m/s ^ 2 in the Arctic region
Note: The gravity acceleration of the lunar surface is about 1.62 Mb/s ^ 2, about 1/6 of the Earth's gravity.
