3rd grade Balanced and Unbalanced Force

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to move in the direction of the stronger force.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the pull between Earth and objects on it.

Front

What is a claim?

Back

A claim is a proposed answer to a question or a statement that can be supported by evidence.

Front

What happens when balanced forces act on an object?

Back

When balanced forces act on an object, it does not move or change its motion.

Front

What happens when unbalanced forces act on an object?

Back

When unbalanced forces act on an object, it accelerates in the direction of the stronger force.

Front

Can you give an example of balanced forces?

Back

An example of balanced forces is a book resting on a table; the weight of the book is balanced by the upward force of the table.

Front

Can you give an example of unbalanced forces?

Back

An example of unbalanced forces is when a child pushes a toy car; if the push is stronger than the friction, the car will move.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often caused by contact with another surface.

Front

What is the role of air resistance?

Back

Air resistance is a type of friction that acts against objects moving through the air, slowing them down.
