Assignment: Balanced and Unbalanced Forces

Which non-contact force is acting on the framed picture?

• Magnetic Force – The force between magnetic materials, such as a magnet pulling a metal paperclip without touching it.
• Gravitational Force – The force that attracts objects toward each other, like the Earth's gravity pulling objects downward.
• Electrostatic Force – The force between electrically charged objects, like a balloon attracting hair after being rubbed on a sweater.
• Static Force – The force between statically charged objects, like a balloon attracting hair after being rubbed on a sweater.

How will this object move?

• It will not move.
• It will move to the right.
• It will move to the left.

Which would be an example of a balanced force?

Why does a book on a table not move?

• The book does not move because no forces are acting on the book.
• The book does not move because gravity is the only force acting on the book.
• The book does not move because the force of the table is pushing up and gravity is pulling down.
• The book does not move because the force of the table is strong.

Which could be an example of an unbalanced force?

• A plate sitting on a dining table.
• Earth orbiting the Sun.
• A ball at the top of a hill that is not moving.
• A baseball that has been thrown to home plate.

if an object is not moving, the forces acting upon it are…

• balanced forces.
• unbalanced forces.
• noncontact forces.
• magnetic forces.

Which picture is displaying a balanced force, the top or the bottom?

• the top picture
• the bottom picture
