What determines the gravity of an object?

Back

Gravity is determined by the mass of the object and the distance from the center of the object to the center of the Earth.

Front

In an electrically neutral object, what is true about protons and electrons?

Back

In an electrically neutral object, the number of protons is equal to the number of electrons.

Front

What happens when two balloons are rubbed with a wool cloth and held near each other?

Back

The balloons push away from each other because they have the same electric charge.

Front

What particles must an object gain or lose to become electrically charged?

Back

An object can become electrically charged if it gains or loses electrons.

Front

What is charging by friction?

Back

Charging by friction occurs when two objects rub against each other, causing one to gain a positive charge and the other to gain a negative charge.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms or grams.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is an electric charge?

Back

An electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field.

Front

What are the two types of electric charges?

Back

The two types of electric charges are positive and negative.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects.
