F = m * a

where:

* F is the net force acting on the mass (in Newtons, N)

* m is the mass (in kilograms, kg)

* a is the acceleration (in meters per second squared, m/s²)

To find the acceleration, rearrange the formula:

a = F / m

Here's how to apply it:

1. Identify the net force acting on the mass: This is the vector sum of all forces acting on the object. Consider forces like gravity, friction, applied forces, etc.

2. Determine the mass of the object: This is usually given in the problem or can be measured.

3. Substitute the values of force and mass into the formula: a = F / m

4. Calculate the acceleration: This will give you the acceleration in meters per second squared.

Example:

Let's say a 5 kg object is pushed with a force of 20 Newtons. What is the acceleration?

1. Net force: F = 20 N

2. Mass: m = 5 kg

3. Substitute: a = 20 N / 5 kg

4. Calculate: a = 4 m/s²

Therefore, the object will accelerate at 4 meters per second squared.

Additional Notes:

* Acceleration is a vector quantity, meaning it has both magnitude and direction. The direction of the acceleration is the same as the direction of the net force.

* If the net force is zero, the object will not accelerate (it will remain at rest or continue moving at a constant velocity).

* This formula is applicable to objects moving in a straight line. For objects moving in a circle, the formula for centripetal acceleration is used instead.
