Forces of Gravity and Magnetism

The video explains the differences between gravity and magnetism. Gravity is a force due to mass, while magnetism arises from moving charged particles and magnetic materials. Gravity always attracts, whereas magnetism can attract or repel depending on the poles. Gravity is weaker compared to the strong force of magnetism. The video concludes with a call to action for viewers to subscribe and like.

What is the primary condition for gravity to occur?

• Presence of electric current

• Movement of charged particles

• Presence of mass

• Presence of magnetic materials

Which of the following is true about the interaction between two masses?

• They can repel each other

• They always attract each other

• They can either attract or repel

• They have no interaction

In magnetism, what happens when like poles are brought close to each other?

• They attract each other

• They repel each other

• They have no effect on each other

• They merge into one pole

What is a unique feature of magnetism that is not present in gravity?

• It is always attractive

• It is weaker than gravity

• It has poles

• It involves mass

Which force is generally stronger, gravity or magnetism?

• Neither, they are both weak

• Both are equally strong

• Magnetism is stronger

• Gravity is stronger
