Both gravitational and electric field obey inverse square laws (e.g. F(grav)=GMm/r^2 and F(electric)=kq1q2/r^2 where GMm and kq1q2 are constants). They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge.
What are two similarities between gravity and electricity?
Both act in a vacuum. Both are central and conservative. Both obey an inverse-square law .
What are the similarities and differences between gravitational electric and magnetic field?
They both have a point source, and with this point source they both have a field intensity that is proportional based on the inverse square law. Both exert force from a distance with no contact.
What are two major similarities or differences between gravitational force and electrical force?
Electric vs Gravitational Force
|Both have fields||Electric force can be both repulsive and attractive but gravity only attracts|
|Both have potential lines||Electric force results from charge but gravitational force results from mass|
What are two differences between gravitational and electromagnetic fields?
Gravity is a weak force, but has only one sign of charge. Electromagnetism is much stronger, but comes in two opposing signs of charge. … Electromagnetic waves, meanwhile, are typically generated by small movements of charge pairs within objects, and have wavelengths much smaller than the objects themselves.
How are gravitational and electromagnetic forces alike?
There are many similarities between electromagnetic (EM) radiation and gravitational radiation: both travel at the speed of light; both carry energy away from their sources; both consist of transverse waves with two polarizations.
What is the difference between gravitational and electrical forces?
The basic difference between gravitational and electrostatic force is that:Gravitational force is the force by which earth attracts other objects by mass. … While electrostatic force is the force of an object due to charge. It is also conservative force.
How will you compare the gravitational field and the electric field produced by a proton?
The Gravitational Field is the same strength as the Electric Field. The Electric Field is stronger and is in the same direction as the Gravitational Field. … The Gravitational Field is stronger and is in the same direction as the Electric Field.
