An object at rest will stay at rest,and an object in motion will stay in motion at constant velocity,unless acted upon by an unbalanced force.
Gravity is always acting on an object.Like for example the soccer ball has gravity,the force is keeping it still.
If you kicked a ball in space,it would keep going forever,because there is no gravity,friction or air resistance going against it.
But on earth, since there is gravity the soccer ball will stop by a person.When a soccer ball is resting non moving on the ground,it will stay like that until someone kicks it or another force acts upon it.
Less weight the ball has,the fastest it goes.
The more weight the ball has,the slower it goes.
The second law of motion states that the acceleration of an object is dependent on the mass of the object as well as the force applied.
This means that the heavier the soccer ball or the weight it has the slowest it goes when you kick it.
With more force and gravity the soccer ball will come to a stop,but in space it will go forever till it hit's something.
The third Law of motion states that for every action,there is an equal and opposite reaction involved.
Gravity is always acting on the soccer ball while on Earth.
When you kick a soccer ball,it goes forward.If someone from the other team kicks the ball at the same time as you the one who puts more force behind the kicks ends up with it.
