Non Contact Forces Review

Front

What is a non-contact force?

Back

A non-contact force is a force that acts between two objects that are not touching each other.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, depending on their masses and the distance between them.

Front

How can you determine which system has greater gravitational attraction?

Back

The system with the larger mass or closer proximity between the objects will have greater gravitational attraction.

Front

What does it mean for an object to be electrically neutral?

Back

An object is electrically neutral when it has equal numbers of positive and negative charges.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charges on the surface of an object.

Front

What are examples of non-contact forces?

Back

Examples of non-contact forces include gravitational force, magnetic force, and electric force.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the relationship between mass and gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction.

Front

What is the formula for gravitational force?

Back

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

Front

What is the role of electric charges in static electricity?

Back

Electric charges, when accumulated on an object, create static electricity, which can result in attraction or repulsion between objects.
