SSC MTS EXAM

Detailed explanation-1: -Newton suggested that objects like the soccer ball have a natural tendency to keep moving. The only reason they stop, he believed, is because an unbalanced force acts on them. By an unbalanced force, Newton meant the force applied to the soccer ball by its environment.

Detailed explanation-2: -Inertia is the tendency of an object to resist a change in its motion. A soccer ball will remain resting on the grass until a force acts on it (a kick). Once it is kicked, the soccer ball’s inertia will keep it going because the ball RESISTS changing its motion.

Detailed explanation-3: -In soccer, friction force prevents the ball from moving the forward or backward direction forever when it is kicked by the player. This is based on the fact that the soccer ball rubs against the ground causing a resistance force (friction) which slows the ball down.
