ResourcesChapter menu Projectile Motion and Gravity Projectile motion is the curved path an object follows when it is thrown or propelled near the surface of the Earth. Projectile motion has two components—horizontal motion and vertical motion. These components are independent, so they have no effect on each other. Section 1 Gravity and Motion Chapter M2

18. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Projectile Motion and Gravity, continued Horizontal Motion is a motion that is parallel to the ground. When you throw a ball, your hand exerts a force on the ball that makes the ball move forward. This force gives the ball its horizontal motion. Section 1 Gravity and Motion Chapter M2

19. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Projectile Motion and Gravity, continued Vertical Motion is motion that is perpendicular to the ground. A ball in your hand is prevented from falling by your hand. After you throw the ball, gravity pulls it downward and gives the ball vertical motion. Section 1 Gravity and Motion Chapter M2

Inertia and Newton’s First Law Newton’s first law is sometimes called the law of inertia. Inertia is the tendency of all objects to resist any change in motion. Chapter M2

28. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Newton’s First Law of Motion, continued Mass and Inertia Mass is a measure of inertia. An object that has a small mass has less inertia than an object that has a large mass. So, changing the motion of an object that has a small mass is easier than changing the motion of an object that has a large mass. Section 2 Newton’s Laws of Motion Chapter M2

29. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Newton’s Second Law of Motion The acceleration of an object depends on the mass of the object and the amount of force applied.

Newton’s third law of motion can be simply stated as follows: All forces act in pairs. Chapter M2

36. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Newton’s Third Law of Motion, continued Section 2 Newton’s Laws of Motion Force Pairs Do Not Act on the Same Object A force is always exerted by one object on another object. This rule is true for all forces, including action and reaction forces. Action and reaction forces in a pair do not act on the same object. If they did, the net force would always be 0 N and nothing would ever move! Chapter M2

37. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Newton’s Third Law of Motion, continued All Forces Act in Pairs—Action and Reaction Newton’s third law says that all forces act in pairs. When a force is exerted, there is always a reaction force. Section 2 Newton’s Laws of Motion Chapter M2

38. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Newton’s Third Law of Motion, continued The Effect of a Reaction Can Be Difficult to See When an object falls, gravity pulls the object toward Earth and pulls Earth toward the object. You don’t notice Earth being pulled upward because the mass of Earth is much larger than the mass of the object. Thus, the acceleration of Earth is much smaller than the acceleration of the object.

41. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu Momentum, Mass, and Velocity The momentum of an object depends on the object’s mass and velocity.

43. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu The Law of Conservation of Momentum The law of conservation of momentum states that any time objects collide, the total amount of momentum stays the same. Objects Sticking Together After two objects stick together, they move as one object. The mass of the combined objects is equal to the masses of the two objects added together. Section 3 Momentum Chapter M2

44. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu The Law of Conservation of Momentum, continued The combined objects have a different velocity because momentum is conserved and depends on mass and velocity. So, when the mass changes, the velocity must change, too. Section 3 Momentum Chapter M2

45. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu The Law of Conservation of Momentum, continued Objects Bouncing Off Each Other When two objects bounce off each other, momentum is usually transferred from one object to the other. The transfer of momentum causes the objects to move in different directions at different speeds. Section 3 Momentum Chapter M2

46. Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu The Law of Conservation of Momentum, continued Conservation of Momentum and Newton’s Third Law Conservation of momentum can be explained by Newton’s third law. Because action and reaction forces are equal and opposite, momentum is neither gained or lost in a collision. Section 3 Momentum Chapter M2

The game could be played on a small field for a few hours or on a huge tract of land for several days. The game was not just for fun—in fact, it was often used as a substitute for war.
