What Is Acceleration?
Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, having both magnitude and direction, and is measured in meters per second squared (m/s²). A positive value indicates speeding up in the chosen direction, while a negative value indicates slowing down or accelerating in the opposite direction.
Formulas
- a = Δv / t = (v_f − vᵢ) / t - From change in velocity and time
- a = F / m - From net force and mass (Newton's second law)
Units
- váµ¢, v_f - Velocity (meters per second, m/s)
- t - Time (seconds, s)
- F - Force (newtons, N)
- m - Mass (kilograms, kg)
- a - Acceleration (meters per second squared, m/s²)
