  • Newton's First Law states that an object in motion will come to rest unless acted upon by an unbalanced force.
    False
  • A larger object has less inertia than a smaller object.
    False
  • A system at rest experiences no acceleration.
    True
  • What is the relationship between inertia and mass?
    Directly proportional
  • What is another name for Newton's First Law?
    Law of Inertia
  • A system at rest is in a state of equilibrium
  • Match the concept with its description:
    Uniform motion ↔️ Constant velocity with no net force
    Equilibrium ↔️ Net force is zero
    Newton's First Law ↔️ Law of Inertia
  • What is the first step in applying Newton's First Law to solve a problem?
    Identify all forces
  • The inertia of an object is directly proportional to its mass
  • Inertia is an object's tendency to resist changes in its state of motion
  • Why does a system in uniform motion maintain constant velocity?
    No net force
  • A system at rest experiences no net force.

    True
  • An object at rest will remain at rest unless acted upon by an unbalanced force.
    True
  • How does inertia relate to the mass of an object?
    Directly proportional
  • What is static equilibrium characterized by?
    Zero net force and torque
  • A box on a table is an example of static equilibrium.
    True
  • What is another name for Newton's First Law?
    Law of Inertia
  • What are the two states of motion described in Newton's First Law?
    Rest and uniform motion
  • What does it mean for a system to be at rest according to Newton's First Law?
    No net force
  • A car moving at a constant speed on a level road is an example of a system in uniform motion.
  • A system in uniform motion maintains a constant velocity because there is no net force
  • What is the tendency of an object to resist changes in its state of motion called?
    Inertia
  • A system at rest has no acceleration.

    True
  • Dynamic equilibrium occurs when an object is in uniform motion
  • Match the scenario with the equilibrium condition:
    Box on a table ↔️ Static equilibrium
    Car moving at constant speed ↔️ Dynamic equilibrium
