What is acceleration?
Acceleration is the rate at which speed changes: how much faster (or slower) something moves each second. The SI unit is the meter per second squared (m/s²): an acceleration of 1 m/s² adds 1 m/s of speed every second.
Accelerations are often compared with standard gravity, g = 9.80665 m/s², the acceleration of a freely falling object near the Earth's surface. Pilots, astronauts and roller-coaster designers talk about "g-forces": at 3 g you feel three times your normal weight.

Frequently asked questions
What is 1 g in m/s²?
Standard gravity is exactly 9.80665 m/s², about 32.174 ft/s².
How many g can a person withstand?
Most people lose consciousness at around 4–6 g sustained head-to-foot; fighter pilots with g-suits handle about 9 g. Very brief impacts can be much higher.
What is 0 to 60 mph in 5 seconds in g?
About 0.55 g (26.8 m/s ÷ 5 s ≈ 5.4 m/s²).
