- Is Deceleration Really a Forbidden Word in Physics?
One participant compares the term deceleration to the concept of cold, suggesting that while it may lack scientific precision, it is widely understood and useful in everyday language Participants do not reach a consensus on the validity of the term deceleration Multiple competing views remain regarding its definition and usefulness in physics
- Kinematics: time for a given acceleration, deceleration and distance . . .
The discussion revolves around a kinematics problem involving a train that accelerates and decelerates over a fixed distance, with the goal of determining the minimum time for this motion Participants explore the relationship between acceleration, deceleration, and distance, questioning the implications of these variables on the time taken for the journey Exploratory, Assumption checking
- How to calculate vehicle deceleration (time to stop)
To calculate the distance a bike will roll after stopping pedaling, use kinematic equations that incorporate deceleration and road grade The primary equations are: a = (vf - vi) t for deceleration, t = (vf - vi) a for time, and d = vi*t + 1 2*a*t^2 for distance To account for the incline, the equation modifies to d = vi*t + 1 2*a*t^2 + (g*sinθ*t^2) 2, where g is 9 8 m s² and θ is the

- Calculate Car Deceleration and Stopping Distance - Physics Forums
The discussion focuses on calculating the deceleration and stopping distance of two cars involved in a braking scenario Car 1, traveling at 50 km hr, decelerates at -12 05 m s² after slamming on the brakes and stops in 8 meters Using the same deceleration, Car 2, initially traveling at 100 km hr, takes 32 meters to stop The final analysis confirms that the two cars remain 13 meters apart
