| If some body with mass m was at rest, or moved uniformly and rectilinearly, and then began to move with some acceleration a, this means that a certain force F acted on the body. This is due to Newton’s second law:
a = F / m.
Therefore, the correct answer is: we judge by the presence of acceleration in the body.
