| File info: Forces and motion In physics, a force is any effect that can change the motion of an object. Forces can be externally acting, such as the force a person exerts on a ball, or they can be internal forces, such as the force of gravity. Motion is the change in position of an object over time. The movement can be rectilinear or rotational. Newton Isaac Newton (1643-1727) is an English scientist considered one of the greatest scientists in history. Newton made fundamental contributions to mathematics and physics, including his law of gravitation and the three laws of motion. Newton's laws of motion Isaac Newton presented three laws of motion that describe the relationship between forces and motion. Newton's first law Newton's first law states that an object at rest remains at rest, and an object in motion remains in motion, unless acted upon by some force. Newton's second law Newton's second law states that the acceleration experienced by an object is directly proportional to the force acting on it and inversely proportional to its mass. Newton's third law Newton's third law states that for every action there is an equal and opposite reaction. Acceleration Acceleration is the rate of change of velocity. Acceleration is expressed in meters per second squared (m/s²). Examples of forces and motion When you push a ball, you exert a force on it that makes it move. When a ball falls from a height, the force of gravity causes it to accelerate toward the ground. When a wheel spins, centrifugal force makes it move in a circle. Applications of forces and motion Forces and motion are used in a variety of applications, including: Mechanical Engineering: Uses forces and motion to design and build machines. Physics: Forces and motion are used to understand the movement of objects. Astronomy: Forces and motion are used to understand the movement of planets and stars. the future The study of forces and motion continues to evolve as science and technology advance. Future research may lead to a better understanding of the fundamental forces that govern the universe. | ||
