This resource is a complete lesson that covers Gravitational Fields for the OCR A Level Physics A course. However, it is useful for other exam boards too.
This lesson teaches the following content:
-gravitational fields are due to objects having mass
-modeling the mass of a spherical object as a point mass at its centre
-gravitational field lines to map gravitational fields (uniform and radial)
-the concept of gravitational fields as being one of a number of forms of field giving rise to a force
-Newton’s law of gravitation; F = -(GMm)/r² for the force between two point masses (inverse square law)
This lesson includes:
-A full presentation including 2 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
