Question
Darnell has a tree house. A bucket on a pulley is used to lift objects into the tree house. Which type of force lifts the bucket? A. push B. friction C. gravity D. pull
Solution
The type of force that lifts the bucket into the tree house is D. pull. Here's why:
-
When Darnell pulls on the rope attached to the pulley, he is exerting a pulling force. This force is transmitted through the rope and pulley system to the bucket.
-
This pulling force overcomes the force of gravity that is pulling the bucket downwards.
-
The bucket then moves upwards, towards the tree house.
So, the correct answer is D. pull.
