Forces and Interactions: Understanding Motion and Stability

• Interactions between objects can cause changes in motion and stability in systems at any scale.
• Forces, which can be measured by their strength and direction, can cause a change in motion of one or both interacting objects.
• The total force on an object is the vector sum of all forces acting on it.
• Newton's third law states that for any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first but in the opposite direction.
• The momentum of an object is defined as its mass times its velocity and is conserved within an isolated system of interacting objects.
• Forces between objects arise from gravity, electromagnetism, and strong and weak nuclear interactions.
• Collisions between objects involve forces that can change their motion, while objects in contact exert electromagnetic forces on each other.
• Gravitational, electric, and magnetic forces between objects do not require contact and can be mapped by their effect on a test object.
• Gravitational forces are always attractive and governed by Newton's law of universal gravitation.
• Electric and magnetic forces are different aspects of a single electromagnetic interaction and can be attractive or repulsive.
• Stability and instability in physical systems depend on the balance of competing effects, and a system can be static, changing, or have a stable repeating cycle of changes.
• The conditions and properties of objects within a system affect the rates of energy transfer and how fast or slowly a process occurs.
