What is an example of unbalanced forces?

Back

An example of unbalanced forces is when two forces acting on an object are not equal in size or direction, causing the object to accelerate in the direction of the larger force.

What happens when two like poles of magnets face each other?

Back

When two like poles of magnets face each other, they will repel each other.

Front

How can you determine if forces are balanced or unbalanced in a picture?

Back

Forces are balanced if they are equal in size and opposite in direction, resulting in no change in motion. If they are not equal, the forces are unbalanced, causing acceleration.

What is the definition of balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in the object's motion.

Front

What is the definition of unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Can you give an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table; the force of gravity pulling the book down is balanced by the normal force of the table pushing it up.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is the role of gravity in forces?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.
