What is Acceleration?
Acceleration is how fast something speeds up or slows down. When you press the gas pedal in a car, the car accelerates. When you hit the brakes, the car decelerates (negative acceleration). Acceleration tells us how much the speed changes in a certain amount of time.

Frequently Asked Questions
What is the difference between acceleration and velocity?
Velocity is how fast something moves. Acceleration is how fast the velocity changes. A car going 60 mph has velocity. When it speeds up from 60 to 70 mph, that's acceleration.
Why is g-force important?
G-force shows acceleration compared to Earth's gravity. It helps us understand how much force people feel. For example, 2g means twice the force of gravity.
What is Earth's gravity in different units?
Earth's gravity is 9.81 m/s², 32.2 ft/s², 1 g-force, 981 Gal, 127,139 km/h², or 290,888 mph². This is the acceleration of falling objects.
Can acceleration be negative?
Yes! Negative acceleration means slowing down (deceleration). When you brake in a car, you have negative acceleration in the direction you're moving.
What acceleration can humans safely handle?
Humans can safely handle about 5g for short periods. Fighter pilots can handle up to 9g with special suits. Above 10g becomes dangerous without protection.
How accurate is this acceleration converter?
Our converter uses precise conversion factors and provides results accurate to 8 decimal places, suitable for most scientific and engineering needs.

Quick Reference
What is Acceleration?
Acceleration is how fast something speeds up or slows down. Think of it like this - when you press the gas pedal in a car, you feel pushed back into your seat. That feeling is acceleration!
In simple words, acceleration tells us how much the speed changes in one second. If a car goes from 0 to 60 mph in 6 seconds, we can calculate its acceleration.
The basic formula is: Acceleration = Change in Speed ÷ Time
Key Points:
- Acceleration measures how speed changes
- It can be positive (speeding up) or negative (slowing down)
- Units are meters per second squared (m/s²)
- Even changing direction at constant speed is acceleration
How Does Acceleration Work?
Acceleration happens when a force acts on an object. The bigger the force, the more acceleration you get. This is why a sports car can accelerate faster than a heavy truck.
Positive Acceleration
When something speeds up. Like a car leaving a traffic light or a ball rolling down a hill.
Negative Acceleration
When something slows down. Like a car braking or a ball rolling up a hill.
The acceleration calculator helps you find out exactly how much acceleration is happening in any situation.
Real Life Examples of Acceleration
Car Acceleration
A typical car accelerates at about 3 m/s² when you press the gas pedal normally.
Falling Objects
Everything falls at 9.8 m/s² on Earth due to gravity. This is the same for a feather and a rock in a vacuum!
Running Start
A sprinter can accelerate at about 9 m/s² at the start of a race.
Bicycle Riding
When you pedal hard, a bicycle accelerates at about 2-3 m/s².
Emergency Braking
A car can decelerate at -8 m/s² during emergency braking.
Rocket Launch
Space rockets accelerate at about 30 m/s² during launch!

Acceleration Formulas Made Simple
Basic Formula
Acceleration = (Final Speed - Starting Speed) ÷ Time
This is the most common formula. Use it when you know the starting speed, ending speed, and time.
Distance Formula
Use when you know distance, starting speed, and time
This formula helps when you know how far something traveled and want to find acceleration.
Example Calculation
A car goes from 0 to 30 m/s in 10 seconds. What's the acceleration?
a = (30 - 0) ÷ 10 = 3 m/s²
The car accelerates at 3 meters per second squared.
Why is Acceleration Important?
Understanding acceleration helps us in many ways:
Car Safety
Engineers use acceleration to design safer cars and better brakes.
Sports Performance
Athletes train to improve their acceleration for better performance.
Space Travel
Rockets need precise acceleration calculations to reach space.

Common Questions About Acceleration
What's the difference between speed and acceleration?
Speed tells you how fast you're going right now. Acceleration tells you how quickly your speed is changing. You can have high speed but zero acceleration if you're going at a constant speed.
Can acceleration be negative?
Yes! Negative acceleration means slowing down. When you hit the brakes in a car, you have negative acceleration (also called deceleration).
Why do we measure acceleration in m/s²?
Because acceleration is speed change per second. Speed is measured in m/s, so acceleration (change in speed per second) is m/s per second, which equals m/s².
Is gravity an acceleration?
Yes! Gravity accelerates objects toward Earth at 9.8 m/s². This means every second, a falling object gets 9.8 m/s faster.
How accurate is this calculator?
Our acceleration calculator is very accurate for basic physics problems. It uses the standard physics formulas that scientists and engineers use every day.
