Acceleration Formula:
| From: | To: |
Acceleration is the rate of change of velocity with respect to time. It measures how quickly an object's velocity is changing, either in magnitude or direction. Acceleration is a vector quantity with both magnitude and direction.
The calculator uses the acceleration formula:
Where:
Explanation: The formula calculates the average acceleration over a time interval by dividing the change in velocity by the time taken for that change.
Details: Acceleration calculations are fundamental in physics and engineering for analyzing motion, designing vehicles and machinery, understanding forces, and solving kinematics problems in various applications from automotive engineering to space exploration.
Tips: Enter final velocity and initial velocity in meters per second (m/s), and time in seconds (s). Time must be greater than zero. Positive acceleration indicates speeding up, negative acceleration indicates slowing down.
Q1: What is the difference between acceleration and velocity?
A: Velocity is the rate of change of position, while acceleration is the rate of change of velocity. Velocity tells us how fast and in what direction an object is moving, while acceleration tells us how quickly that velocity is changing.
Q2: What does negative acceleration mean?
A: Negative acceleration (deceleration) means the object is slowing down. If the acceleration is in the opposite direction to the velocity, the object will decrease its speed.
Q3: Can acceleration be zero when velocity is not zero?
A: Yes, an object can have constant velocity (zero acceleration) while moving. For example, a car cruising at a constant speed on a straight road has zero acceleration.
Q4: What are the units of acceleration?
A: The SI unit of acceleration is meters per second squared (m/s²). Other common units include cm/s², ft/s², and g (where 1g = 9.8 m/s²).
Q5: How is instantaneous acceleration different from average acceleration?
A: Average acceleration is calculated over a finite time interval, while instantaneous acceleration is the acceleration at a specific moment in time, calculated as the derivative of velocity with respect to time.
