The first law states an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force. According to Newton’s third law of motion, “To every action, there is an equal and opposite reaction.” This means that whenever an object interacts with any other object, there exists a pair of interaction forces acting on both objects. Two examples of natural forces are gravity and magnetism. It is a flat surface that is sloped rather than horizontal. The slide, fireman’s pole, tire swing, and merry-go-round are all examples of forces. Some objects move on their own, and there are other objects that need help to move. Question 2. Because force is connected to motion, various levels of force applied to these motion examples shows how differences in force contribute to differences in motion. 10.2 BALANCED AND UNBALANCED FORCES Have you even seen a game of tug-of-war (Fig. Given m is the mass of the object and g is the acceleration due to gravity. The sum of all forces acting on the object along a line is never equal to zero. • Describe the motion of an object based on its position, direction and speed.
