Acceleration Definition:

The rate at which an object’s velocity changes over time is called acceleration. Due to its vector nature, it includes both direction as well as a magnitude. The changes in direction, speed, or both can result in acceleration.

Acceleration Formula:

The formula for calculating acceleration is:

Acceleration = Change in Velocity / Change in Time

If the velocity of an object is constant, the acceleration is zero. Positive acceleration indicates speeding up, while negative acceleration (or deceleration) indicates slowing down.

Acceleration Units:

The SI unit for acceleration is meters per second squared (m/s²).
Other common units include :
  • kilometers per hour squared ( km/h²)
  • feet per seconds squared (ft/s²)
  • centimeters per seconds squared (cm/s²)

What is Average Acceleration?

Average Acceleration Formula:

The formula for calculating average acceleration is:

Average Acceleration = (Final Velocity – Initial Velocity ) / Time
  • Final Velocity : This is the velocity of an object at the end of a certain time interval.
  • Initial Velocity: This is the velocity of an object at the beginning of a certain time interval.
  • Time : This is the duration for which the motion occurs.

Velocity : Velocity describes the rate of change of position of an object with respect to time. It has both magnitude (speed) and direction. The SI unit of velocity is meters per second (m/s).

The Formula for velocity is :

Velocity = Change in Displacement / Change in Time

This velocity formula tells you how much the position of an object changes per unit of time.

Time :Time is a scalar quantity that represents the duration of events. It is one of the fundamental dimensions in physics and is typically measured in seconds (s).

Types of Acceleration:

  • Tangential Acceleration : In circular motion, an object may experience changes in its tangential speed. Tangential acceleration represents the rate of change of tangential velocity.Tangential Acceleration Calculator

  • Centripetal Acceleration : In circular motion, objects also experience centripetal acceleration directed towards the center of the circular path.

  • Angular Acceleration : In rotational motion, angular acceleration describes the rate at which an object’s angular velocity changes over time.

  • Gravitational Acceleration : It is the constant rate at which an object near the Earth’s surface accelerates due to the force of gravity.

How an Acceleration Calculator Works: A Step-by-Step Example

Question :

A car accelerates from an initial velocity of 12.5 km/h to a final velocity of 56km/h in a time of 12 seconds. Calculate the acceleration of the car.

Answer:
Given:
  • Initial velocity (u) = 12.5 km/h
  • Final velocity (v) = 56 km/h
  • Time (t) = 12 seconds

First, let’s convert the velocities to meters per second (m/s) since the standard unit for acceleration is m/s².
Convert initial velocity (u) from km/h to m/s :

  • u = 12.5 km/h × (1000 m / 1 km) × (1 hour / 3600 sec)
  • u = 3.472 m/s
Convert final velocity (v) from km/h to m/s:
  • v = 56 km/h × (1000 m / 1 km) × (1 hour / 3600 sec)
  • v = 15.556 m/s
Now, use the formula for acceleration:

Acceleration (a) = ( Final velocity (v) − Initial velocity (u)) / time (t)
a = (15.556 m/s − 3.472 m/s) / 12s
a ≈ 12.084 m/s / 12s
a ≈ 1.007 m/s²
Therefore, the acceleration of the car is approximately 1.007 m/s².
