Question

A box slides down a frictionless plane inclined at an angle θ ¸ above the horizontal. The gravitational force on the box is directed
a)vertically.
b)perpendicular to the plane.
c)at an angle θ ¸ below the inclined plane.
d)parallel to the plane in the same direction as the movement of the box.
e)parallel to the plane in the opposite direction as the movement of the box.

Answer 1

Answer:

vertically

Explanation:

The gravitational force on any object will always be vertically. (at an angle 90-θ below the inclined plane).

The force made by the inclinated plane on the box and the force made by the box on the plane will be perpendicular to the plane.

The force made by the inclinated plane on the box and the force made by the box on the plane will be perpendicular to the plane.The acceleration of the box will be parallel to the plane in the same direction as the movement of the box, and the fricction force will be eparallel to the plane in the opposite direction as the movement of the box.
