Question

PROJECTILE MOTION - Horizontal Motion

(in the x-direction)
Give the equation for:
1. Displacement
2. Velocity
3. Acceleration

Answer 1

Displacement in horizontal motion is given by x = x₀ + Vₓt, velocity remains constant as Vₓ = V₀x, and acceleration is zero (aₓ = 0) since no horizontal forces are acting on the projectile.ₓ

Step-by-step explanation:

When analyzing the horizontal motion of a projectile, it's essential to consider that the horizontal acceleration (aₓ) is zero, indicating a constant horizontal velocity. Hence, you can use the following kinematic equations specific to horizontal motion:

• Displacement (x): x = x₀ + Vₓt, where x₀ is the initial horizontal position, Vₓ is the horizontal velocity, and t is the time.
• Velocity: Vₓ = V₀x = Uₓ, where V₀x is the initial horizontal velocity and remains constant throughout the motion.
• Acceleration: aₓ = 0, since there are no horizontal forces acting on the projectile.

These equations are helpful for solving problems in projectile motion where the projectile is subject to gravity but not any additional horizontal forces.
