Newton's Laws of Motion

• If two bodies exert forces on each other, these forces have the same magnitude but opposite directions
• A body remains at rest or in motion at a constant speed in a straight line, unless acted upon by a force (correct)
• The time rate of change of its momentum equals the force
• A body in motion tends to stay in motion

• They provide the mathematical formula for gravity
• They describe the relationship between energy and matter
• They explain the motion of physical objects and systems (correct)
• They discuss the properties of light and color

• 1756
• 1800
• 1623
• 1687 (correct)
