On the Board: a Plan for the study of new
material. Expected result.
Today in the lesson we
will look at the analogy between the electric and gravitational field,
identify similarities and differences.
material:The concept of field is one of the most important
physical concepts. It replaces the model of "action at a distance"
and allows us to explain physical phenomena using a purely local cause and
effect – an object (mass) does not fall, because The earth at a distance
attracts it to itself and the local gravitational field of the Earth exerts
force on it. Since students are familiar with gravitational fields(at least
in their effects), they need to use them as an analogy for an electric field.
the gravitational field of the Earth they are familiar with, enter a
representation of the force line for both the Central field (for the Earth)
and the uniform field (for example, in a room on The earth's surface).
simple electrostatic experiments can be used to demonstrate electrostatic
forces between charged objects. The same should be done with the
gravitational field, and at the end of this work, students should understand
how to draw a diagram of the force line to represent the electric field near
a uniformly charged positive or negative area (or point charge). It may also
be worth demonstrating and discussing friction, contact, and induction
electrification with students.
the electric field strength is determined, do the same with the gravitational
E =F/qo (Н/Кл)
g = F/m (Н/кг)
it is necessary to highlight that: the charge is the source of the electric
field, and the electric field acts on the charges. Mass is the source of the
gravitational field, and gravitational fields affect the masses.
Invite students to create a table of similarities
and differences between the gravitational and electrostatic fields, which
should reflect the following:
1. Sources of electrostatic and gravitational
2. The force acting on a body in the
gravitational and electrostatic field
3. Power characteristics of electric and
gravitational fields (formula and direction).
4. Schematic representation of gravitational and
5. Graph of the dependence of the intensity
of these fields on the distance from the charge and the inverse square of

this stage, a differentiated approach to learning is implemented.

to check learners’ learning?
Differentiation – how do you plan
to give more support? How do you plan to challenge the more able learners?
