Question

If there is friction everywhere , then why does an object fall to the ground due to gravity? Why does friction not oppose gravity and not allow it to fall?

Answer 1

If gravity is the only force acting on an object, then we find the object will accelerate at a rate of 9.8 m/${\mathrm{s}}^2$ down toward the center of the Earth. But due to the presence of friction force and air resistance its speed slows down.
