Question

Select the correct answer.

When a cup is placed on a table, which force prevents the cup from falling to the ground?
A.
gravitational force
B. normal force
C.
resistance force
D.
tension force

Answer 1

B. Normal Force

Step-by-step explanation:

Gravitational force is what keeps us from floating off while normal force is the support force exerted on an object that's in contact with another stable object. So if the cup is resting on a table, then the table is exerting an upward force (normal force) on the cup in order to support the weight of the book.
