Periodic table of elements metals and nonmetals questions

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. Make your claim and support it with evidence/reasoning. Write using complete sentences. 1st Law - Law of Inertia

2nd Law - Law of Force and Acceleration

3rd Law - Law of Action-Reaction

A student made the table shown to list some contact and non-contact forces.


Examples of Forces
Contact Forces Non-Contact Forces
The force exerted by a stretched spring The force applied by Earth and sun on each other
The electrical force exerted by a positive charge on a negative charge Magnetic attraction between two magnets


Which statement best explains why the table is incorrect?
Spring force is a force acting at a distance.
Electrical force is not a contact force.
Gravitational force can act between planets and sun only when they are in contact.
Magnetic attraction is a contact force
