    • Non-contact forces act without direct physical contact.

      True
    • The acceleration of an object is directly proportional to its mass.
      False
    • Arrange the following terms in order from their fundamental concepts to their definitions:
      1️⃣ Position
      2️⃣ Velocity
      3️⃣ Acceleration
    • Velocity includes both speed and direction

    • What is the unit for acceleration?
      m/s²
    • Friction is a contact force that opposes motion
    • What does the conservation of momentum state for a closed system?
      Total momentum remains constant
    • Match the concept with its definition and units:
      Momentum ↔️ Product of mass and velocity, kg·m/s
      Velocity ↔️ Rate of change of position, m/s

      9.81 \, \text{m/s}^2</latex>
    • Static friction opposes the initial motion between stationary surfaces.

      True
    • What is momentum defined as?
      Product of mass and velocity
    • In a displacement-time graph, the slope represents the velocity of the object.
    • The area under an acceleration-time graph represents the change in velocity
    • Friction is an example of a contact force.
    • A car at rest will remain at rest unless acted upon by an unbalanced force.
    • What does the slope of a displacement-time graph represent?
      Velocity
    • The area under a velocity-time graph represents the object's displacement.
      True
    • Contact forces require direct physical contact
    • Newton's first law is also known as the law of inertia
    • An object in motion will stop immediately unless acted upon by an unbalanced force.
      False
    • What is the unit for acceleration?
      m/s²
    • What are the two main types of forces?
      Contact and non-contact
