1) According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. Inertia is the propensity to resist changes in a condition of motion.
2) There is an equal and opposite reaction force for every action, according to Newton's third law of motion. This means that while the athlete pushes against the track, the track makes the athlete ahead with an equal and opposing force.
3) Newton's second law of motion states that an object's acceleration is determined by the net force being applied to it divided by its mass. When the group of an item and the net force acting on it are known, the acceleration of that object can be determined using this equation for acceleration.
4) The resultant acceleration of the ball due to the force of the tennis racquet on the ball is determined by Newton's Second Law, which links the external force on an object to the item's subsequent acceleration.
5) First Law of Motion of Newton (Inertia) Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace.
6) Thrust is the ball's movement caused by the racquet's momentum. The weight of the ball is applied downward from the ball's center of gravity by gravity. Drag is a term used to describe a force, in this case, air resistance, acting in the opposing direction of an object's motion.
7) The imparting of spin on the ball during a hit is made possible by friction between a racquet's strings and a tennis ball. Furthermore, the ball's bounce is impacted by friction between it and the surface.
8) Tennis can be played because of the gravitational force. Without gravity, the ball wouldn't be hit and wouldn't fall and bounce on the court. Because the force of gravity acts on a tennis ball, it is continually accelerating.
