The force o A that keeps your feet from sliding as you walk is A. centripetal force B. weight C. kinetic friction. D. static friction. 10. If the net force on an object is zero, A. there must be no forces acting on the object. B. the object must be at rest. C. the object's acceleration must be zero. D, there can be no friction acting on the object. 11. You push on a block on frictionless ice with a force of 8 N, causing it to accelerate at 2 m/s2. The mass of the block is A. 2 kg. B. 4 kg C. 8 kg. D. 16 kg 12. Starting from rest, a 2 kg body acquires a speed of 8 m/s in 2 seconds. The net force acting on the body is D. 16 N 13. Two forces of 4 N and 12 N act on a body simultaneously. The net forc A. 4 N B. 12 N. C. 16 N. D. impossible to tell from the given information.Explanation / Answer
In physics, action at a distance is the concept that an object can be moved, changed, or otherwise affected without being physically touched (as in mechanical contact) by another object. That is, it is the nonlocal interaction of objects that are separated in space.
Gravity is one that force which act at a distance on an object without touching it.
Whenever there is a field, there is force at a distance. Why? Because it's the field that carries that force from the source to a target where the force is effected.
For example, W = mGM/r^2 = mg; where g is the gravity field that carries the weight force W from the source mass M to the target mass m. And the distance that force is carried is shown by r, the center to center distance between m and M.
ANS B. Weight (force of gravity).
