Learn how tension and friction interact when an object moves at constant velocity. This video breaks down the force balance, explains why acceleration is zero, and shows how physics principles apply ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

We're at the Porsche test track to learn all about acceleration. Unit 2 Segment C: Acceleration and Kinematic Equations We're back at the Porsche test track to learn all about acceleration. Kinematic ...

\(\Delta v\) (pronounced 'delta v' is the change in speed of the object. Acceleration is measured in metres per second per second or metres per second squared \(m\, s^{-2}\). A sprinter starting at ...

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 ...
