Physics - Vectors

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

What is the resultant of two or more vectors?

Back

The resultant is the vector sum of two or more vectors.

Front

What function is used to find the angle when given the adjacent and hypotenuse sides?

Back

cos^-1 (inverse cosine) is used to find the angle.

Front

What is the formula for the y-component of a vector F at an angle θ?

Back

The y-component is given by F sin(θ).

Front

What is the formula for the x-component of a vector F at an angle θ?

Back

The x-component is given by F cos(θ).

Front

What is the significance of the angle in vector resolution?

Back

The angle determines the direction of the vector components.

Front

How do you calculate the magnitude of the resultant vector?

Back

Use the Pythagorean theorem: R = √(Rx² + Ry²), where Rx and Ry are the components.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.

Front

What is the tangent function used for in vector problems?

Back

The tangent function (tan) is used to find angles when the opposite and adjacent sides are known.

Front

What is the relationship between the sides of a right triangle and the angles?

Back

The sides of a right triangle are related to the angles through trigonometric functions: sin, cos, and tan.
