Theme of the lesson

The law of universal gravitation .Gravitational Potential

Learning objectives that are achieved at this lesson(Subject Programme reference)

to explain the characteristic curve of the gravitational intensity and potential of material point and the distance;

to use the law of universal gravitation in problem solving.

Lesson objectives

LO Physics Define the work done and recall GPE=mgh;

Language objective Describe Gravity as a field offorce using appropriate terminology;

Draw equipotential lines between two distant astronomical objects.

Assessment criteria

Could explain the characteristic curve of the gravitational intensity and potential of material point and the distance;

could use the law of universal gravitation in problem solving.

Language objective

MUST: remember key words

SHOULD: describe relationships of field strength with help

COULD: describe relationships of field strength independently and how this affects physical phenomena using technical vocabulary

Concentration of attention

Post a lesson goal.

Students define keywords on topic.

1.How far away from the earth must an orbiting spacecraft be for

the astronauts inside to be weightless? Explain.

2.  A space station astronaut is working outside the station as it orbits the earth. If he drops a hammer, will it fall to earth? Explain why or why not.

3.  The free-fall acceleration at the surface of planet 1 is 20 m/s2. The radius and the mass of planet 2 are twice those of planet 1. What is g on planet 2?

4.  Why is the gravitational potential energy of two masses negative? Note that saying “because that’s what the equation gives” is not an explanation.

Advanced students can assist other students with problems. Advanced students can research information of the interference of sea waves that form ‘rough waves’

Question of students and review of questions related to the learning objects. Student will be asked questions during the activity, notebooks will be reviewed, homework will be checked and exam questions related to this topic will be reviewed.
