When an object does not start at rest, you need to measure both the initial velocity and the final velocity to be able to calculate the acceleration. One way to to do this is to use a double mask. A ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

Let's start with some simple physics. Drag racing, in fact most vehicle dynamics, are governed by Newton's Second Law (NSL) with the basic equation, F=ma, stating the relationships of force, mass and ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...
