Watch this video to find out more about forces that can act on objects without touching them. Gravitational forces that make things fall down to the ground – unless another force stops them. An apple ...

Most of us take gravity as an assumed part of our living realities, but why? Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept of ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...

At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...

There are few sports more exciting than playoff baseball, but behind every pitch there is also a fascinating story of physics. From gravity to spin, the science shaping the game can be just as ...
