The force acting on the object at is .

Explanation:

Given that object has a constant mass in time, the force acting on the object (), in newtons, is defined by following expression:

(1)

Where:

- Mass, in kilograms.

- Acceleration, in meters per square second.

By definition of acceleration, we know that:

(2)

Let suppose that given vector velocity is expressed in meters per second. If we know that , and , then the force acting on the object is:

The force acting on the object at is .
