    Investigating the factors related to the crater formed by a falling object.

    As a result, the force of impact of the ball on the surface will increase because all the potential energy will be changed into kinetic energy (velocity) of the ball just before its impact on the sand. This increase in the force of impact will move more sand sideways and downwards resulting in the formation of a bigger bowl shaped crater, hence the increase in diameter. Variables * The independent variable is the drop height of the ball. * The dependent variable is the diameter of the crater formed by the impact of the ball on the sand.

"The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers."

-Brian Greene

If you want to learn about the physical laws that govern the behaviour of everything in the universe, then chances are you'd enjoy studying physics as part of your IB diploma. Physics is one of six subjects on offer in group 4, and gives students a grounding in the scientific method, lab work, and range of theoretical concepts. The theory portion begins with building blocks like mechanics, electric currents, and waves, and builds up to advanced topics like astrophysics and particle physics.

Physics will require a fair amount of writing, often in the form of lab reports. If you need to refine your writing skills, come visit our collection of student-submitted IB physics papers. Study the teacher-marked and peer-reviewed papers alongside your own work, and before long, you'll know how to edit and re-write assignments to your teachers' high standards.

Students who get good marks in physics, and especially in high level physics, will leave school well positioned to apply for a range of university course within the physical and biological sciences.
