Projectile Motion summary

The video tutorial explains projectile motion, highlighting its parabolic path due to constant gravity and no air resistance. It breaks down the velocity of a projectile into horizontal (VX) and vertical (VY) components, and provides equations for determining the position of the projectile at any time. Initial conditions are discussed, along with the constant gravitational acceleration of 9.81 m/s².

What shape does the path of a baseball take when it undergoes projectile motion?

• Parabolic

• Linear

• Circular

• Elliptical

Which of the following assumptions is made in projectile motion?

• Variable air resistance

• Constant gravity

• Constant air resistance

• Variable gravity

How does the vertical component of velocity (VY) change over time in projectile motion?

• It increases linearly

• It remains constant

• It decreases due to gravity

• It oscillates

What is the formula for the horizontal position (X) of a projectile at any time T?

• X = X0 - 1/2 * GT^2

• X = VY0 * T - 1/2 * GT^2

• X = X0 + VX0 * T

• X = X0 + VY0 * T
