The gravity of Earth, which is denoted by g, refers to the acceleration that the Earth imparts to objects on or near its surface. In SI units this acceleration is measured in metres per second squared ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used. Watch this ...

An object can possess energy as a result of its motion, position and deformation. On Earth, the force of gravity is always acting upon you. When you are above the Earth's surface you have potential ...

In the Star Wars films, Obi-Wan Kenobi describes ‘The Force’ as “an energy field created by all living things. It surrounds us and penetrates us; it binds the galaxy together.” If that sounds exotic, ...
