Question

What is resultant force? Give an example where resultant force is zero

Answer 1

friction is the resultant force. example of resultant force when it is zero is : when the surface is very rough or very smooth it is resultant force which is zero.

Answer 2

Answer:

In physics and engineering, a resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces. The resultant force on the car is zero. Other examples include: a runner at their top speed experiences the same air resistance as their thrust. an object falling at terminal velocity experiences the same air resistance as its weight.
