In order to get a feel for this formula, we ask the following question. Stopping Times: The physics of stopping a moving vehicle - such as a bike or car - is vitally important every day. With an increase in mass, the braking distance of a car a) Increases b) Decreases c) Stays the same d) Goes up and down . Source:en.wikipedia.org . d = - 20 m/s 2. Changing the mass of a car does not change the thinking distance but the braking distance is changed as the mass of a car changes. 6.7 stopping distances. GCSE Physics Online. s = speed in km/h. Shop. 1. Stopping Distance Formula Concept of Stopping Distance: Stopping distances are a favourite part of … This lesson will explore the physics behind the distance it takes to stop a moving car. The chart shows the thinking, braking and stopping distances for the two cars. Occasionally the time taken to stop is given, too. The distance it takes a vehicle to stop takes into account both the reaction time of the driver (this affects the thinking distance) and also the braking … If you need the formula sheet or physics notes to refer to while attempting the worksheet below, you may browse through this Blog site to find related study material.
