According to Newton's Third Law of Motion, when one object exerts a force on another object, what happens?
Each object experiences a force that is the same strength as the force acting on the other object but in the opposite direction.
What is the nature of the force pairs between objects according to Newton's Third Law of Motion?
Equal in strength and opposite in direction
What is the relationship between the force experienced by each object when one object exerts a force on another?
The force experienced by each object is the same strength as the force acting on the other object but in the opposite direction.
What is the effect of forces on objects according to Newton's Third Law of Motion?
Each object experiences a force that is the same strength as the force acting on the other object but in the opposite direction.
What is the nature of the relationship between force and acceleration according to Newton's Third Law of Motion?
The force experienced by an object is directly proportional to its acceleration.
According to Newton's Third Law of Motion, when one object exerts a force on another, how does each object experience the force?
Each object experiences a force that is the same strength as the force acting on the other object but in the opposite direction.
What is the relationship between the force pairs between objects, as described by Newton's Third Law of Motion?
The force pairs between objects are of the same strength but act in opposite directions.
What is the nature of the force experienced by each object when one object exerts a force on another, according to Newton's Third Law of Motion?
The force experienced by each object is of equal strength as the force acting on the other object and in the opposite direction.
What is the effect of forces on objects, as described in the context of Newton's Third Law of Motion?
Forces on objects cause them to exert an equal force in the opposite direction.
What is the relationship between force and acceleration as described in the context of Newton's Third Law of Motion?
Force and acceleration are directly proportional according to Newton's Third Law.
Study Notes
Ecosystems and Biodiversity
- The ecosystem that covers less than 10% of the Earth's surface but contains about 90% of the world's species is the coral reef ecosystem.
- Marine biodiversity is usually higher near coral reefs.
- Biodiversity is usually greater near the equator.
- Biodiversity encompasses the variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
- Deforestation has had a primary result of reducing biodiversity.
Newton's Third Law of Motion
- When one object exerts a force on another object, the second object always exerts an equal and opposite force on the first object.
- The force pairs between objects are equal in magnitude and opposite in direction.
- The force experienced by each object is equal in magnitude and opposite in direction.
- The effect of forces on objects is that they always occur in pairs, with one object exerting a force on another and the second object exerting an equal and opposite force on the first.
- The relationship between force and acceleration is that force causes acceleration, and the more massive an object is, the more force is required to achieve a given acceleration.
- When one object exerts a force on another, each object experiences an equal and opposite force.
- The force pairs between objects are equal in magnitude and opposite in direction.
- The force experienced by each object is equal in magnitude and opposite in direction.
