Questions and Answers

What is the definition of a force based on classical mechanics?

  • A force is the resistance to motion.
  • A force is the visible interaction between two objects.
  • A force is the energy stored in an object.
  • A force quantifies the tendency of objects to move towards their preferred configuration. (correct)
  • How do we deduce the existence of a force?

  • By directly seeing the force.
  • By measuring the force's energy.
  • By analyzing the force's color.
  • By observing its effect on objects. (correct)
  • How are forces defined according to Newton's laws of motion?

  • $F = kx$, where $F$ is the force, $k$ is the spring constant, and $x$ is the displacement.
  • $F = \frac{mv^2}{r}$, where $F$ is the force, $m$ is the mass, $v$ is the velocity, and $r$ is the radius.
  • $F = m/v$, where $F$ is the force, $m$ is the mass, and $v$ is the velocity.
  • $F = ma$, where $F$ is the force, $m$ is the mass, and $a$ is the acceleration. (correct)
