Newton's Third Law and Gravity

The video tutorial discusses whether Newton's Third Law can be applied to gravitational force. It explains Newton's Third Law, which states that every action has an equal and opposite reaction. The tutorial confirms that this law holds true for gravitational forces, as when Earth exerts a force of attraction on an object, the object exerts an equal force back on Earth. The explanation is detailed and aims to clarify the concept for students.

What is the main question discussed in the video?

• Can we apply Newton's Law of Universal Gravitation to motion?

• Can we apply Newton's Second Law to gravitational force?

• Can we apply Newton's Third Law to gravitational force?

• Can we apply Newton's First Law to gravitational force?

According to Newton's Third Law, what happens for every action?

• There is a greater reaction

• There is an equal and opposite reaction

• There is no reaction

• There is a similar reaction

Which of the following best describes Newton's Third Law?

• For every action, there is an equal and opposite reaction

• For every action, there is a greater reaction

• For every action, there is a lesser reaction

• For every action, there is no reaction

Does Newton's Third Law apply to gravitational force?

• No, it only applies to mechanical forces

• Yes, it applies to all types of forces

• Yes, but only under certain conditions

• No, it only applies to electromagnetic forces

What force does Earth exert on an object according to the video?

• A force of attraction

• A repulsive force

• No force

• A neutral force

When Earth exerts a force of attraction on an object, what does the object do?

• Exerts a lesser force on Earth

• Exerts no force on Earth

• Exerts a greater force on Earth

• Exerts an equal and opposite force on Earth

What is the relationship between the forces exerted by Earth and an object?

• The forces are unequal and in the same direction

• The forces are unequal and opposite

• The forces are equal and in the same direction

• The forces are equal and opposite

What does Newton's Third Law imply about the interaction between Earth and an object?

• Only the object exerts a force

• Both exert equal and opposite forces on each other

• Neither exerts a force

• Only Earth exerts a force

What is the key concept used to explain the question in the video?

• Newton's First Law

• Law of Universal Gravitation

What is the conclusion about Newton's Third Law and gravitational force?

• Newton's Third Law does not apply to gravitational force

• Newton's Third Law applies to gravitational force

• Newton's Third Law only applies to mechanical force

• Newton's Third Law only applies to electromagnetic force
