What is the Tip to Tail Method in vector addition?

Back

The Tip to Tail Method is a graphical way to add vectors by placing the tail of one vector at the tip of the previous vector, allowing for the resultant vector to be drawn from the tail of the first vector to the tip of the last vector.

How do you calculate displacement when given multiple movements in different directions?

Back

Displacement is calculated by determining the net change in position, taking into account the direction of each movement. It is the straight-line distance from the starting point to the final position, along with the direction.

Front

What is a Resultant Vector?

Back

A Resultant Vector is the single vector that represents the sum of two or more vectors, showing the overall effect of the combined vectors in terms of magnitude and direction.

Front

Define a Vector in physics.

Back

A Vector is a quantity that has both magnitude (size) and direction, represented graphically by an arrow.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that represents the total path length traveled, while displacement is a vector quantity that represents the shortest straight-line distance from the initial to the final position, along with the direction.

Front

How do you find the magnitude of a vector?

Back

The magnitude of a vector can be found using the Pythagorean theorem if the vector components are known. For a vector with components (x, y), the magnitude is calculated as √(x² + y²).

Front

What is the significance of direction in vector quantities?

Back

Direction is crucial in vector quantities because it determines how the vector interacts with other vectors and affects the resultant vector when multiple vectors are combined.

Front

Explain how to resolve a vector into its components.

Back

To resolve a vector into its components, you can use trigonometric functions: the horizontal component (x) is found using cosine, and the vertical component (y) is found using sine, based on the angle of the vector.

Front

What is the graphical representation of vectors?

Back

Vectors are graphically represented as arrows, where the length of the arrow indicates the magnitude and the direction of the arrow indicates the direction of the vector.

Front

What is the formula for calculating the resultant of two vectors at an angle?

Back

The resultant R of two vectors A and B at an angle θ can be calculated using the formula: R = √(A² + B² + 2ABcos(θ)).
