What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., temperature, mass), while vector quantities have both magnitude and direction (e.g., velocity, force).

Front

How do you find the resultant displacement of two vectors?

Back

To find the resultant displacement, add the vectors using vector addition, considering their directions.

Front

What is the formula for calculating the components of a vector?

Back

For a vector V at an angle θ, the components are Vx = V * cos(θ) and Vy = V * sin(θ).

Front

What is the significance of the x and y components in vector analysis?

Back

The x and y components allow for the analysis of vectors in a two-dimensional space, simplifying calculations and understanding of motion.

Front

How do you determine the direction of a resultant vector?

Back

The direction of a resultant vector can be determined using trigonometric functions, typically by calculating the angle using the arctangent of the ratio of the y-component to the x-component.

Front

What is the vertical component of a vector?

Back

The vertical component of a vector is the part of the vector that acts in the vertical direction, typically represented as Vy.

Front

What is the horizontal component of a vector?

Back

The horizontal component of a vector is the part of the vector that acts in the horizontal direction, typically represented as Vx.

Front

How do you calculate the magnitude of a resultant vector?

Back

The magnitude of a resultant vector can be calculated using the Pythagorean theorem: R = √(Vx² + Vy²).

Front

What is the role of angles in vector components?

Back

Angles determine the direction of the vector components and are essential for calculating the x and y components using trigonometric functions.
