5. As a truck moves down the road the driver slams on the brakes to avoid hitting a cat. The fuzzy dice hanging on his mirror swing toward the window. The motion of the dice show a) Newton's first law of motion. d) the universal e) cats are "big b) Newton's second law time" trouble. law of gravitation. of motion. c) Newton's third law of motion.
Newton's first law of motion: Newton's first law of motion, also known as the law of inertia, states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion at the same speed and in the same direction unless acted upon by an external force. In simpler terms, it describes how objects behave when no force is applied to them.
Second law of motion: Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This law is often expressed using the equation F = ma, where F represents the force applied to the object, m is the mass of the object, and a is the resulting acceleration. In essence, it explains how the motion of an object changes when a force is applied to it.
Third law of motion: Newton's third law of motion states that for every action, there is an equal and opposite reaction. This law means that when one object exerts a force on a second object, the second object exerts a force of the same magnitude but in the opposite direction on the first object. Essentially, it describes the reciprocal nature of forces between two objects in a system.
Law of gravitation: This law describes how massive objects attract each other.
1. Every mass attracts every other mass with a force directly proportional to the product of their masses (m1 and m2)
2. The force of attraction is inversely proportional to the square of the distance (r) between their centers of mass.
