Two Dimensional Motion

Q: What are the two types of motion in one dimension?

• Horizontal Motion (Motion in x): Motion along the x-axis (left to right or right to left).

• Vertical Motion (Motion in y): Motion along the y-axis (up and down).

Flashcard 2: What is Two-Dimensional Motion?

A: Two-dimensional motion occurs when an object moves in both horizontal (x-axis) and vertical (y-axis) directions at the same time.

Q: Give an example of two-dimensional motion.

A: A ball thrown diagonally moves both along the x-axis (horizontal) and the y-axis (vertical).

Q: How are vectors expressed in two-dimensional motion?

A: Vectors like velocity, displacement, acceleration, and force are broken down into their x and y components.

Q: How do you determine the velocity in two-dimensional motion?

A: Break the velocity into two components:

1. X Component (Vx): Velocity along the x-axis (horizontal direction).

2. Y Component (Vy): Velocity along the y-axis (vertical direction).

Q: What is the resultant vector in two-dimensional motion?

A: The resultant vector (R) represents the combined effect of the x and y components and is the hypotenuse of the triangle formed by these components.

Q: What does the angle (θ) of a two-dimensional vector represent?

A: The angle (θ) indicates the direction and tilt of the resultant vector.

Q: What are non-collinear vectors?

A: Non-collinear vectors are vectors that do not lie along the same line and can point in different directions.

Q: What happens when two vectors are perpendicular (90°)?

A: The magnitude of the resultant vector can be determined using the Pythagorean Theorem:

Q: What are the components of a two-dimensional vector?

A:

1. X Component (Vx): The part of the vector along the x-axis (horizontal).

2. Y Component (Vy): The part of the vector along the y-axis (vertical).
