Basic Law of Mechanics
- The basic law of mechanics is Newton's First Law of Motion, also known as the Law of Inertia.
- This law states that an object at rest remains at rest, and an object in motion remains in motion, unless acted upon by an external force.
Characteristics of Force
- Force is a push or pull that causes an object to change its motion or shape.
- Force has both magnitude (amount of force) and direction.
Equilibrium of Forces
- Two forces are in equilibrium when they are equal in magnitude and opposite in direction.
- When two forces are in equilibrium, the net force acting on an object is zero, and the object remains stationary or continues to move with a constant velocity.
Kinematics
- Kinematics is the study of the motion of objects without considering the forces that cause the motion.
- Kinematics involves the description of motion in terms of displacement, velocity, acceleration, and time.
Resultant of Two Forces
- The resultant of two forces is a single force that has the same effect as the two original forces acting together.
- The resultant force is found by vector addition of the two forces, taking into account their magnitudes and directions.
