Question

consider this situation: a block is at rest on an inclined plane. of the forces listed, identify which act upon the block. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

• Normal force: The inclined plane exerts a normal force perpendicular to its surface on the block.
• Gravity: The Earth's gravitational pull acts vertically downward on the block.
• Friction: Since the block is at rest on the inclined plane, static friction acts parallel to the plane (opposing the tendency of the block to slide down due to the component of gravitational force along the plane).
• Applied force: There is no mention of an external applied force on the block in the given situation.
• Tension: There is no rope or string attached to the block (no indication of tension - related setup).
• Air resistance: There is no mention of motion through air (like falling or being pushed at high speed) where air resistance would be significant.

Answer:

Normal, Gravity, Friction
