Explain the difference between gravity, static electricity, and magnetism in regards to the direction of their force. What do all three forces have in common? What is the weakest of the three?
Gravity is a force of attraction that pulls objects toward each other, always acting in the direction between the centers of mass of the two objects. It is a universal force that acts on all objects with mass.
Static electricity is a force that results from the interaction of electric charges that are not in motion. It can attract or repel objects with opposite or like charges, respectively. The force of static electricity acts along the line connecting the charges.
Magnetism is a force of attraction or repulsion that acts between magnetic materials. Like charges repel each other, while opposite charges attract. The force of magnetism also acts along the line connecting the magnets.
All three forces involve the interaction between objects but differ in the type of interaction and the direction of the force they exert on the objects. Gravity and magnetism involve forces of attraction, while static electricity involves both attraction and repulsion.
Out of the three forces, static electricity is typically considered the weakest since its effects are often only noticeable with very light objects or in specific conditions. Gravity is the strongest force of attraction, while magnetism has a medium strength compared to the other two forces.
