Kinematics in 2-Dimensions

Question 1

Simple Ideas of Projectile Motion

Answer 1

1. X and Y motion can be solved separately.
2. Time links the x motion with the y motion.
3. Velocity in the x direction is constant.
4. Y motion is Freefall.
5. Vertical velocity is zero at the apex. Horizontal velocity remains constant.
6. Y vs. X position is a parabola.

Question 2

Answer 2

A quantity with both direction and magnitude.

Question 3

What are vector components?

Answer 3

The x-direction and y-direction vectors that when added together create the original vector.
