1st: The law of inertia
Example
An example of this law could be present in a ball rolling on the ground that maintains its motion till infinity if no external force acts on it; however, the friction acting on the ball from the outside helps to break the motion of the ball and brings it to rest.
This law could also be seen if an object is thrown in outer space. Becuase it tends to move in a direction to infinity. This is because outer space lacks environment, air, and the force of gravity. This means that if the object does not receive any resistance to the motion, it will continue to move until it hits another object.
"An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless a unbalanced force is present."
Forces present
-
Net force
If all the forces acting in the object are balanced the object will stay at rest or continue to move at a constant speed. But if the forces are unbalanced, the object will accelerate in the direction of the net force, this change could make the object speed up, slow down, or change direction.
Free-body diagram
Is a representation of an object with all the forces that act on it, the external enviroment, the forces that the object exerts on other objects.
Example
A car parked on an inclined hill can be an example of this. Where the gravitational force is pulling it downward, the normal force perpendicular to the slope surface and a frictional force opposing the car's motion down the slope.
