Question

when drawing a free - body diagram for an object on an inclined surface, which way does the force of gravity point?
a. parallel to the surface
b. straight up
c. perpendicular to the surface
d. straight down

Explanation:

The force of gravity, also known as weight, always acts vertically downward towards the center of the Earth. This is a fundamental property of gravitational force. In the context of a free - body diagram for an object on an inclined surface, while other forces (like normal force perpendicular to the surface and frictional force parallel to the surface) may have directions related to the surface, the force of gravity remains straight down.

Answer:

D. Straight down
