Different forces can really change how energy works in moving objects. Let's look at them one by one:
Gravity is always there, pulling on everything. When you throw something up, gravity pulls it back down. This changes motion energy (the energy of moving things) into stored energy (like when it's high up). When it comes back down, that stored energy turns back into motion energy.
Friction is like a little force that doesn't want to let things move easily. It happens when two surfaces touch and rub against each other. Friction changes motion energy into heat energy. For example, when you slide a book on a table, it eventually stops because of friction. This means some energy disappears into the surrounding air instead of keeping the book moving.
When you push or pull something, you're using a force on it. If your push or pull is stronger than the friction, you can make the object move faster. For example, when you kick a soccer ball, you're applying a force. If your kick is strong enough to beat the friction, the ball speeds up. We can understand this better with the simple idea:
Work = Force x Distance
When things move through the air, they face air resistance, which tries to slow them down. This force also changes motion energy into heat energy, just like friction. This is why things like skydiving can be a bit challenging.
In short, the energy of moving objects keeps changing because of different forces like gravity, friction, pushing or pulling, and air resistance. Each of these forces is important for deciding how much energy an object has and how it moves.
