Non Contact Forces Review

Front

What type of charge does a substance have if it has more electrons than protons?

Back

A negative charge.

Front

What happens to gravitational force as mass increases?

Back

Gravitational force increases.

Front

What type of charges do two balloons with the same charge have?

Back

Like charges.

Front

What is static electricity?

Back

The buildup of electric charges on an object.

Front

What physical quantity never changes regardless of location in the universe?

Back

Mass.

Front

What is the relationship between electric charge and the number of protons and electrons?

Back

An object is positively charged if it has more protons than electrons, and negatively charged if it has more electrons than protons.

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What happens to the electric force between two charged objects as the distance between them increases?

Back

The electric force decreases.
