There are a variety of sports which display newton's second law of motion. One of the primary examples is Rugby. In rugby, players will attempt to tackle each other to gain possession of the rugby ball. To do this, they need to estimate how much force they need to exert to tackle the player with minimal damage. Although the player will not calculate F=ma while tackling, he will approximate using newton's second law. The law states that force is directly proportional to acceleration, and mass is inversely proportional. This means that the greater the mass of an object, the more force is needed to accelerate this body. In rugby, the average player weighs about 120 kg. A safe acceleration which does not harm the player while still forcing him to the ground is 2m/s^2. Thus, the force needed to tackle a player safely is 240 N. Apart from rugby, many other sports display newton's second law, including Bowling, shot put, discus, javelin, football, and tennis.
