Force is a physical quantity that describes the interaction between objects and their tendency to change their state of motion. It is measured in newtons (N) and is represented by the symbol F.

Mass is a fundamental property of matter that measures its resistance to acceleration when a net force is applied. It is measured in kilograms (kg) and is represented by the symbol m.

Acceleration is the rate of change of an object's velocity over time. It is measured in meters per second squared (m/s²) and is represented by the symbol a.

The relationship between force, mass, and acceleration is described by Newton's second law of motion. According to this law, the net force acting on an object is equal to the product of its mass and acceleration:

```

F = ma

```

In this equation, F represents the net force acting on the object in newtons (N), m represents the mass of the object in kilograms (kg), and a represents the acceleration of the object in meters per second squared (m/s²).

This equation tells us that the greater the mass of an object, the greater the force required to accelerate it. Conversely, the greater the acceleration of an object, the greater the force required to produce it.
