Concept explainers
A stone is shown at rest on the ground.
a. The vector shows the weight of the stone. Complete the vector diagram showing another vector that results in zero net force on the stone.
b. What is the conventional name of the vector you have drawn?
(a)
To Complete: The vector diagram.
Explanation of Solution
Introduction:
The component of the contact force which is normal to the surface of the contact, is known as the normal force.
As shown in the above figure, it cancels out the weight of the stone. Hence, the net force on the stone is zero.
(b)
Conventional name of the vector that is drawn.
Answer to Problem 46A
Normal Vector
Explanation of Solution
Introduction:
The contact force which is normal to the surface of the contact, is known as the Normal force.
The conventional name of the vector is Normal Vector.

Average acceleration is always halfway between the initial acceleration of an object and its final acceleration. Average acceleration is always equal to the change in velocity of an object divided by the time interval. Average acceleration is always equal to the displacement of an object divided by the time interval. Average acceleration is always equal to the change in speed of an object divided by the time interval.arrow_forward
