![]() Most production street vehicles have a maximum braking around 0.8 g's. A reasonably skilled driver can stop at 20 ft/sec 2 (0.62 g's). Many safety experts use 15 ft/sec 2 (0.47 g's) as the maximum deceleration that is safe for the average driver to maintain control, good to excellent tires, dry surface. Measured on a dry flat surface starting at 60 mph. Maximum braking varies from -3 to -5 meters/sec2 (-7 to -11 mph/sec), or about -0.3 to -0.5 g's. Average acceleration is 60 mph per 5 seconds which equals 12 mph per second and equates to +0.55 g's.Ġ to 60 mph in 5 seconds (+0.55 g's) TimeĪdaptive Cruise Control systems, vehicle radar, automatically brake when approaching other vehicles. Top of the line production muscle cars can go from 0 to 60 mph in 5 seconds. Maximum vehicle acceleration depends on tires and horsepower. Maximum braking depends on vehicle weight and tire traction, width and diameter. Sponsored links Vehicle Acceleration and Braking The term "g" is a fixed acceleration baseline for comparison purposes. ![]() Force is mass multiplied by acceleration. By International definition 9.80665 meters per second per second (s 2) is the gravitational acceleration constant, 1g = 9.80665 meters per second per second (m/s 2) exactly.Īcceleration compared to free fall gravity acceleration g's is not a force. The earth is not a perfect sphere and gravity varies slightly depending on location. This is because the gravitational force is an extremely weak force as. Acceleration is the change of velocity over time. The exact acceleration rate varies slightly depending exactly where on earth the object is falling. The gravitational constant denoted by the capital letter G, is an empirical physical constant involved in the calculation of gravitational effects in. \footnotesize a m / F a m/F where: \small a a is the acceleration of the object expressed in metre per second squared \small\rm m/s2 m/s2 \small m m is the mass of an object in kilograms \small \rm kg kg and \small F F is the force measured in Newtons \small \rm N N. We now only have the time derivative of velocity because mass does not change. ![]() Objects falling due to the force of gravity in a free fall increase in speed with time and distance. In addition, the gravitational force formula, the work-energy theorem.
