What are the two factors of gravity and how do they affect gravitational pull?

Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.

  • Objects with greater mass have a stronger force of gravity between them.
  • Objects that are closer together have a stronger force of gravity between them.

How does the force of gravity depend on the distance between two objects?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Why we call the force of gravity an attractive force?

Why is gravity only an attractive force? Because mass is always positive. There are different notions of mass, but they’re equivalent. The masses in Newton’s law of gravitation, F=Gm1m2r2, are gravitational masses.

Why is gravity not repulsive?

We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.

Is gravitation an attractive or repulsive force?

Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive [3].

Is gravity a fictitious force?

Under General Relativity, the force of gravity is replaced by distortions in space itself. Objects move following the curvature of space. At low energies, in an inertial reference frame, that works out to move exactly the same way as under Newtonian gravity. Thus, Newtonian gravity is a “fictitious” force.

Why centrifugal force is called a fictitious force?

We say fictitious because the actual source of the centrifugal acceleration is somewhat indirect and the experience one has results from the unbalanced forces acting on the reference frame, not a force. Note, it is an acceleration not a force. They are not forces and should not be called forces.

Why is the Coriolis effect important?

The Coriolis effect is important to virtually all sciences that relate to Earth and planetary motions. It is critical to the dynamics of the atmosphere including the motions of winds and storms. In oceanography , it helps explains the motions of oceanic currents.

How Coriolis effect takes place?

But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

How do you calculate the Coriolis effect?

In our Coriolis effect calculator, the rotating body is assumed to be Earth with angular velocity ω = 2π/24h ≈ 0.0000727 1/s ( 2π means 360° in radians). If you want to change it, you can go to the advanced mode.

What causes the Coriolis effect answers?

The main cause of the Coriolis effect is the Earth’s rotation. As the Earth spins in a counter-clockwise direction on its axis, anything flying or flowing over a long distance above its surface is deflected. As latitude increases and the speed of the Earth’s rotation decreases, the Coriolis effect increases.

Which of the following is influenced by the Coriolis effect?

Answer: The correct answer would actually be Jet Stream (D). Explanation: This is true because the Coriolis Effect deflects wind from different hemispheres causing it to effect Jet Stream, which are series of air currents.
