Questions and Answers

What is the term for the rate of change in the velocity of an object?

  • Impulse
  • Acceleration (correct)
  • Force
  • Momentum

    • Which of the following is a measure of the magnitude of the change of an object's position over time?

  • Velocity
  • Displacement
  • Acceleration
  • Speed (correct)

    • What is the product of the mass and velocity of an object called?

  • Force
  • Acceleration
  • Momentum (correct)

    Describe the difference between speed and velocity. How does this distinction relate to an object's motion?

    <p>Velocity has both magnitude (speed) and direction. Objects can have zero velocity but still have speed due to change in direction.</p> Signup and view all the answers

    How does an object's acceleration relate to its change in velocity?

    <p>Acceleration is the rate of change of velocity; it is the change in velocity per unit time.</p> Signup and view all the answers

    What is the physical significance of momentum in relation to force and acceleration?

    <p>Momentum is the product of an object's mass and velocity. A force applied to an object changes its momentum, resulting in acceleration.</p> Signup and view all the answers

    Describe the difference between displacement and distance. How are they related to an object's velocity and acceleration?

    <p>Displacement is the net change in an object's position, while distance is the total path traveled. Velocity relates to displacement, and acceleration relates to the change in velocity.</p> Signup and view all the answers

    How does an object's impulse relate to its momentum and force?

    <p>Impulse is the change in an object's momentum, resulting from a force applied over a period of time.</p> Signup and view all the answers
