Questions and Answers

What is the angle between the velocity and acceleration vectors when an object moves in a circle at a constant speed?

  • 90 degrees (correct)
  • 0 degrees
  • 45 degrees
  • Cannot be determined

    • If an object moves along a parabolic path, what can be said about the direction of its acceleration?

  • Zero
  • Always perpendicular to the velocity (correct)
  • Constant in magnitude
  • Always opposite to the velocity

    • For an object moving in a plane, what is the relationship between its velocity and acceleration vectors?

  • The velocity and acceleration vectors are always parallel to each other.
  • The angle between the velocity and acceleration vectors depends on the position of the object in its path. (correct)
  • The direction of the acceleration is always towards the center of the circle in which the object is moving.
  • The velocity and acceleration vectors are always perpendicular to each other.
