Formula

a = (vf - vโ‚€) / t | d = vโ‚€t + ยฝatยฒ | vfยฒ = vโ‚€ยฒ + 2ad

The kinematic equations describe motion with constant acceleration. a = (vf - vโ‚€)/t finds acceleration. d = vโ‚€t + ยฝatยฒ finds displacement. vf = vโ‚€ + at finds final velocity. vfยฒ = vโ‚€ยฒ + 2ad relates velocity and distance without time.

Worked Examples

Example 1: Car Acceleration

Problem:A car accelerates from 0 to 100 km/h (27.78 m/s) in 8 seconds. Find the acceleration and distance.

Solution:a = (vf - vโ‚€) / t = (27.78 - 0) / 8 = 3.47 m/sยฒ\na = 0.354g\nd = vโ‚€t + ยฝatยฒ = 0 + ยฝ(3.47)(64) = 111.11 m

Result:a = 3.47 m/sยฒ (0.354g) | d = 111.11 m

Example 2: Braking Distance

Problem:A car traveling at 30 m/s brakes with deceleration of -6 m/sยฒ. How far does it travel before stopping?

Solution:vโ‚€ = 30 m/s, vf = 0 m/s, a = -6 m/sยฒ\nd = (vfยฒ - vโ‚€ยฒ) / (2a) = (0 - 900) / (-12) = 75 m\nt = (vf - vโ‚€) / a = (0 - 30) / (-6) = 5 s

Result:Braking distance: 75 m | Time to stop: 5 s

Frequently Asked Questions

What is acceleration?

Acceleration is the rate of change of velocity over time, measured in meters per second squared (m/sยฒ). Positive acceleration means speeding up, negative acceleration (deceleration) means slowing down. The formula is a = (vf - vโ‚€) / t, where vf is final velocity, vโ‚€ is initial velocity, and t is time. For example, a car going from 0 to 60 mph (26.8 m/s) in 5 seconds has an acceleration of 5.36 m/sยฒ, or about 0.55 g.
