Regarding their relative strength, this is the example I always like to give:
You've got some bits of tissue on the table. You run a rubber comb through your
hair and pass it over the bits of tissue. They jump up off the table to the comb.
The gravitational force of the whole Earth is pulling them down, and the electrostatic
force of a charged pocket comb is pulling them up. And the comb wins.
Compared to the gravitational force between a pair of 1-kilogram masses, the
electric force between a pair of 1-coulomb charges the same distance apart is
about 10,000,000,000,000,000,000,000,000,000,000,000,000,000 times as strong.
As my freshman Physics prof used to tell us: If every kilogram of mass in the Earth
and your body were coulombs of charge instead, then when you slipped on the ice,
you'd fall down, just as you do now, but you'd fall 1040 harder.

Which force do you compare the electrostatic force to?
Gravitational force.
Compare and contrast the electric force with the gravitational force?
gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force. However, the concept of dark energy, which seem
What is the difference between electeical forces and gravitational forces?
-- Electrical force only cares about the charge on two objects, and ignores their mass. Gravitational force only cares about the mass of two objects, and ignores their charge. -- Electrical force can be attractive or repulsive. Gravitational force can only be attractive.
Is the electrical or gravitational force stronger?
Electrical force is stronger because it acts in all directions, whereas gravity is directed only downward.
What type of force cause a change in motion?
Every force. mechanical, electrical, magnetic, gravitational, etc.
Which force do you compare the electrostatic force to?
Gravitational force.
Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
How does gravitational force acting on the planet compare to the gravitational force acting on the moon due to the planet?
by dancing
What are two forces that you can compare and contrast?
gravitational force & electrostatic force.
What directions can electrical force and gravitational force act?
Electrical can either attract or repel - gravity can only attract.
Compare and contrast the electric force with the gravitational force?

How are gravitational field and an electrical field similar?
The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these bodies.
What is the force of atraction between two atoms?
Gravitational and electrical forces.
What force gravitational or electrical repels as well as attracts?
The gravitational force is only attractive. Electric and magnetic forces can be both attractive and repulsive.
Is the electrical or gravitational force stronger?
Electrical force is stronger because it acts in all directions, whereas gravity is directed only downward.
