About Acceleration
Acceleration is the rate of change of velocity of an object with respect to time. It’s a vector quantity (has both magnitude and direction) and is measured in meters per second squared (m/s²).
Acceleration Formulas:
From velocity and time: a = (vf – vi) / t
From force and mass: a = F / m
Where:
- a = acceleration (m/s²)
- vf = final velocity (m/s)
- vi = initial velocity (m/s)
- t = time (s)
- F = force (N)
- m = mass (kg)
Frequently Asked Questions
Velocity is the speed of an object in a given direction, while acceleration is the rate at which velocity changes over time. Velocity is measured in m/s, while acceleration is measured in m/s².
Yes, negative acceleration (often called deceleration) means an object is slowing down in the positive direction or speeding up in the negative direction.
According to Newton’s Second Law: Force = mass × acceleration (F=ma). This means acceleration is directly proportional to force and inversely proportional to mass.
