A: ### Quick Answer

**A free-body diagram is used in physics to show the direction and relative magnitude of all forces acting upon an object.** Typically, the object is represented by a box or a dot. Arrows are used to show the direction of each force acting on the object.

In the case of a book sitting on a desk, the force of gravity is shown as an arrow pointing down from the bottom edge of the box. The force of the desk pushing upward on the book, called the normal force, is shown by an arrow pointing up from the top edge of the box. For an object in motion, the applied force is shown as an arrow pointing in the direction of motion, and friction is shown as an arrow pointing in the opposite direction from the back edge of the box. Arrows of different lengths are used to indicate the relative magnitude of the various forces.

## What is vector notation?

A:

Full Answer >**Vector notation is a written method for representing quantities that possess both direction and magnitude, such as acceleration.**Vectors are often represented graphically by lines with an arrow pointing in the appropriate direction.Filed Under: - Q:
## How do you draw a rectangular prism?

A:To draw a rectangular prism, determine what direction you want it to face, draw the two ends and connect them with lines using the vanishing point and other principles of perspective. A prism has perfect edges and faces, so you should use a ruler.

## What is the formula for cubic feet?

A:

Full Answer >**The cubic feet formula depends on the shape of the object for which one is calculating volume, but for a cube, v=a^3, where a is the length of one side in feet.**For cylinders and prisms, the formula is the area of the base multiplied by the height.Filed Under: - Q:
## How do you find the area of an object?

A:To calculate area, first determine the shape of the object. Next, apply the correct formula is needed, and substitute the values into the appropriate places. Finally, the equation should be solved to find the number that represents the area.
