ANSWER:
1. Acceleration
2. Law of Action and Reaction
3. Sir Isaac Newton
4. Law of Force and Acceleration
5. Law of Inertia
EXPLANATION:
1. Force = mass x acceleration
2. Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. This is called the law of force and acceleration (force = mass x acceleration).
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. (Source: Britannica.com)
3. Sir Isaac Newton contributed significantly to the field of science over his lifetime. He invented calculus and provided a clear understanding of optics. But his most significant work had to do with forces, and specifically with the development of a universal law of gravity. (source: space.com)
