Gravity is an important force that helps us understand how a homemade catapult works. In 8th-grade physics, learning about how gravity interacts with force and motion can give us a better idea of how things move. When we think of a catapult, we see it as a tool that changes stored energy into moving energy. Let’s see how gravity plays a part in this process.
Potential Energy: When you pull back the arm of a catapult, you are working against gravity. The energy stored in the catapult arm gets higher. We can think of potential energy (PE) like this:
Kinetic Energy: When you let go of the catapult, the stored energy turns into kinetic energy (KE). Kinetic energy pushes the object forward. We can think of it this way:
As soon as the catapult launches the object, gravity begins to pull it downward. This pull of gravity affects the path of the object, determining how far and how high it will go.
The path that the object follows is called its trajectory. Usually, this trajectory looks like a curve or a "U" shape when we think about gravity. When you launch something from a catapult, it doesn’t go straight; instead, it follows a curved path because:
Gravity is a key part of a homemade catapult experiment. It greatly impacts how the object moves through the air. By learning about potential and kinetic energy, and seeing how gravity affects the path and distance, we can see important ideas in physics. These experiments not only help us understand these concepts better but also make learning fun and exciting!
