How does an understanding of gravitational fields allow for humans to explore the solar system?
Why is no work done on a body moving along a circular trajectory?
How does the application of a restoring force acting on a particle result in simple harmonic motion?
What measurements of a binary star system need to be made in order to determine the nature of the two stars?
How is uniform circular motion like—and unlike—real-life orbits?
How is the amount of fuel required to launch rockets into space determined by considering energy?
How can air resistance be used to alter the motion of a satellite orbiting Earth?
What are the benefits of using consistent terminology to describe different types of fields? (NOS)
How can the motion of electrons in the atom be modelled on planetary motion and in what ways does this model fail? (NOS)
Physics utilizes a number of constants such as G. What is the purpose of these constants and how are they determined? (NOS)
Kepler’s three laws of orbital motion
Newton's universal law of gravitation for bodies treated as point masses
conditions under which extended bodies can be treated as point masses
that gravitational field strength g at a point is the force per unit mass experienced by a small point mass at that point
gravitational field lines.
that bodies moving along a circular trajectory at a constant speed experience an acceleration that is directed radially towards the centre of the circle—known as a centripetal acceleration as given bythat circular motion is caused by a centripetal force acting perpendicular to the velocity
that a centripetal force causes the body to change direction even if its magnitude of velocity may remain constant
that the motion along a circular trajectory can be described in terms of the angular velocity ω which is related to the linear speed v by the equation as given by the equation in the data book.
