Newton's 2nd law F=ma explains that objects will move in the direction of the acceleration a. The object is subject to an acceleration, in this case the acceleration is g= GM/r2 toward earth.

Newton discovered this acceleration in. his law of universal Gravitation, F=mGM/r2

This is why objects fall to earth.

F=ma says that the force required to produce an acceleration is proportional to mass. The moon does not move in the direction of the acceleration. It accelerates but contiously misses falling onto the earth because it is moving sideways. For ordinarary falling objects, the force of gravity pulls them down, since they are not moving sideways fast enough to miss the earth. It's the law of gravity working here not the law of motion.

Which of Newtons laws of motion helps explain the Coriolis effect?

Newton's first law of motion helps explain the Coriolis effect. It states that an object in motion will continue moving in a straight line unless acted upon by an external force. This helps explain how the rotation of the Earth influences the movement of air masses that create the Coriolis effect.


What is the description of motion?

This explanation unified the motion of celestial bodies and motion of objects on earth.


The gravitational force on any object near earth's surface?

The gravitational force on any object near Earth's surface is approximately 9.8 m/s^2, directed towards the center of the Earth. This force is responsible for the weight of objects on Earth and is a fundamental force in shaping the motion of objects in the universe.

What is responsible for the patterns of motion of all celestial objects?

Gravity for the real motion, the Earth's rotation for the apparent motion.


What is the weight of 54kg in newtons on earth?

54kg in newtons on earth weighs 529.2 newtons.


On What does the apparent motion of objects in the sky dependent?

The apparent motion of objects in the sky is dependent on the rotation of the Earth. As the Earth rotates on its axis, it creates the illusion that celestial bodies are moving across the sky from east to west. The movement of the Earth around the Sun also affects the apparent motion of objects in the sky over longer periods of time.


How much would 10 newtons be on the moon?

On the moon, the force exerted by 10 newtons would be approximately 1.63 newtons, because the moon's gravity is about 1/6th of Earth's gravity. This means that objects will weigh much less on the moon compared to Earth.


How does newtons law of universal gravitation apply to earth and moon?

it applies to the earth and moon because their two objects in the universe that attract each other.
