Question

Answer the following questions:
1. What is net force?
Zero
2. When the net force is zero?​

Answer 1

Answer:

Hope this answer helps you!

Explanation:

1. The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

2. an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero.

Answer 2

Explanation:

ball freely falling from a height is not experiencing zero net force ,as the ball is constantly experiencing a gravitational force from earth and also accelerating by amount 'g' constantly.

(B) is correct.

All other case contain objects in stationary phase hence zero acceleration , zero net force.
