Question

unit exam - forces
you toss a 1 kg ball upward with
20 n of force. which of the
following force diagrams is correct?
20 n 1 kg 1 kg 20 n 1 kg
20 n

Explanation:

Step1: Analyze the direction of the force

When tossing a ball upward, the applied force is in the upward direction. The first two diagrams show horizontal forces (right and left), which don't match the upward toss. The third diagram has a 20 N force upward, matching the direction of the toss (upward) and the force magnitude (20 N) applied to the 1 kg ball.

Answer:

The third force diagram (with the 20 N force arrow pointing upward from the 1 kg ball) is correct.
