lien is pushing a box across a table. she used a force of 100 n to get the box moving. which force did she overcome to get the box moving?\n the downward force of gravity on the box\n the upward force of the table on the box\n the reaction force on the box\n the push force on the box

lien is pushing a box across a table. she used a force of 100 n to get the box moving. which force did she overcome to get the box moving?\n the downward force of gravity on the box\n the upward force of the table on the box\n the reaction force on the box\n the push force on the box

Answer

Answer:

None of the above options are correct. The force she overcame is the static - friction force between the box and the table.

Brief Explanations:

When an object is at rest on a surface and a force is applied to move it, the force that resists the start of motion is static friction. Gravity acts vertically downward and is balanced by the normal force (upward force of the table on the box) in the vertical direction and does not oppose horizontal motion. The reaction force is the equal - and - opposite force to the push force according to Newton's third law and is not the force being overcome to start the motion.
