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