1. Initial Velocity: When you throw a projectile, you give it an initial upward velocity. This initial velocity is what propels the object upwards, working against the force of gravity.
2. Gravity's Influence: Gravity is constantly acting on the projectile, pulling it downwards. This force slows down the upward motion.
3. The Trade-Off: The projectile continues moving upwards until the force of gravity completely overcomes its initial upward velocity. At this point, the projectile reaches its peak height.
4. The Descent: After the peak, the projectile starts to fall back down, accelerating due to gravity's constant downward pull.
Think of it like this: Imagine throwing a ball straight up in the air. You give it a powerful push upwards. For a brief moment, the upward force you imparted is stronger than gravity's downward pull. This allows the ball to climb higher. However, gravity always works against the ball's upward motion, gradually slowing it down until it eventually stops and begins its descent.
Key Point: The projectile's motion is a combination of its initial upward velocity and the constant downward force of gravity. The initial velocity determines how high it goes, and gravity ultimately brings it back down.
