Introduction to Forces

Question 6 • AA-F26 Physical Science

Emmett is lifting a box vertically. Which forces are necessary for calculating the total force?

Answer
A
Fp, Ff, and Fg
B
Fp and FN
C
Fp, FN, and Ff
D
Fp and Fg

Explanation

For a box being lifted vertically, the relevant forces are the applied lifting force, Fp, upward, and gravity, Fg, downward. The total (net) force is found by subtracting the downward force of gravity from the upward applied force. Normal and friction forces are not needed for this vertical lift.
