Forces and Motion

While studying mechanics, I learned about Newton’s three laws of motion. The first law tells us that an object will remain at rest or move in a straight line at a constant speed unless acted on by an external force. This explains why a car stays still unless you push the gas pedal. The second law helped me understand the relationship between force and acceleration—more force means more acceleration. The third law, “For every action, there is an equal and opposite reaction,” made me think about how things work in real life, like when we walk. We push against the ground, and the ground pushes back with the same force.

By doing experiments, I observed the connection between force and mass. For example, when I moved objects of different weights on the same surface, heavier objects required more force to move. I found these concepts really important because they explain many everyday phenomena.
