Center of mass
Videos
In physics, the center of mass of a distribution of mass in space is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body cont
This toy uses the principles of center of mass to keep balance when sitting on a finger.
Acceleration

In physics, acceleration is a measure of how fast and in what direction an object's speed and direction of motion are changing. It is defined as the rate of change of the velocity. Like velocity, acce

…of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical…
Drag racing is a sport in which specially-built vehicles compete to be the fastest to accelerate from a standing start.
