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, direction, or both. A positive acceleration indicates an increase in velocity, while negative acceleration (deceleration) indicates a decrease.
The calculator uses the acceleration formula:
Where:
Explanation: This formula calculates the average acceleration over a time period 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 predicting object trajectories in various applications from sports to aerospace.
Tips: Enter velocities in meters per second (m/s) and time in seconds (s). Ensure time value is greater than zero. All values should use consistent units for accurate results.
Q1: What's the difference between acceleration and velocity?
A: Velocity measures how fast an object is moving and in what direction, while acceleration measures how quickly the velocity is changing.
Q2: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) occurs when an object is slowing down. The direction of acceleration is opposite to the direction of motion.
Q3: What is constant acceleration?
A: Constant acceleration occurs when velocity changes at a steady rate over time. Many physics problems assume constant acceleration for simplicity.
Q4: How does acceleration relate to force?
A: According to Newton's second law (F=ma), acceleration is directly proportional to the net force applied and inversely proportional to the object's mass.
Q5: What are typical acceleration values in everyday life?
A: Car acceleration: 3-4 m/s², free fall (gravity): 9.8 m/s², elevator: 1-2 m/s², roller coaster: up to 6-7 m/s².
