Question

Why is it easier to open a door by pushing on it far away from the hinge

• A. Because this creates a larger force.
• B. Because this creates a smaller force.
• C. Because this creates a larger torque.
• D. Because this creates a smaller torque.

Answer 1

The correct option is C Because this creates a larger torque.

Opening a door easily is equal to having a larger torque
Torque is defined as Force x distance. Larger the distance from the fixed axis or hinge, larger the torque and hence it is easier to open the door
