Consider this situation: A block is at rest on an inclined
plane. Of the forces listed, identify which act upon the block.
•normal
•gravity
• applied
• friction
•tension
• air resistance
Friction is Present. Since the angled ramp is supporting the block and the block does not move, there is a friction force on the block. Gravity is Present. Since the block has mass, there is a gravitational force on it.
