Learn how to find acceleration using three different methods based on speed, distance, or force. Use the calculator to enter the known parameters and get the acceleration value in SI or Imperial units.
- Yes, acceleration is a vector as it has both magnitude and direction. The magnitude is how quickly the object is accelerating, while the direction...
- If the force the object is being pushed with stays the same, the acceleration will decrease as the mass increases. This is because F/m = a, so as t...
- Yes, acceleration can be negative, which is known as deceleration. Two objects with equal but opposite acceleration will accelerate by the same amo...
- Work out the change in velocity for your given time. Calculate the change in time for the period you are considering. Divide the change in velocity...
- Convert the magnitude of the force into Newtons. Change the mass of the object to kilograms. Divide both values together to find the acceleration i...
- Velocity is the speed with which an object is moving in a particular direction, while acceleration is how the speed of that object changes with tim...

If you’ve ever watched a bright red Ferrari fly ahead of your Honda Civic after a stoplight, you’ve experienced differing rates of acceleration firsthand. Acceleration is the rate of change in the
of an object as it moves. You can calculate this rate of acceleration, measured in meters per second, based on the time it takes you to go from one velocity to another, or based on the mass of an object.
Define Newton’s Second Law of Motion.
Newton’s second law of motion states that when the forces acting on an object are unbalanced, the object will accelerate. This
is dependent upon the net forces that act upon the object and the object’s mass.
Using this law, acceleration can be calculated when a known force is acting on an object of known mass.
Newton’s law can be represented by the equation
is the total force acting on the object,
You can calculate the average acceleration of an object over a period of time based on its velocity (its speed traveling in a specific direction), before and after that time. To do this you need to know equation for acceleration:
a = Δv / Δt
is the change in velocity, and
is the amount of time it took for that change to occur.
The unit for acceleration is meters per second per second or m/s
Acceleration is a vector quantity, meaning it has both a magnitude and a direction.
Understand the Direction of Acceleration.
The physics concept of acceleration doesn't always match how we would use the term in everyday life. Every acceleration has a direction, usually represented as positive if it's UP or RIGHT, and negative if DOWN or LEFT. See if your answer makes sense based on this breakdown:
Understand the Direction of Force.
Remember, a force only causes acceleration

What is the SI unit for acceleration?
SI units are standardized units that are used internationally in scientific writing. When describing acceleration, use the SI units meters per seconds squared (m/s^2).
