Question

linn 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? the upward force of the table on the box the push force on the box the downward force of gravity on the box the reaction force on the box

Explanation:

When pushing a box across a table to make it move, the main force to overcome is friction. Here, the push force is applied to counter - act the resistance that keeps the box stationary. The upward force of the table on the box (normal force) and the downward force of gravity on the box act vertically and balance each other in the vertical direction for a box on a flat table. The reaction force on the box is a result of Newton's third - law and is not the force that needs to be overcome to start the box moving. The push force is what initiates the motion by overcoming the static friction. In this context, the push force on the box is the force that overcomes the opposing force to get the box moving.

Answer:

the push force on the box
