Balanced and Unbalanced Forces, Friction, and Gravity

Front

What are 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 motion.

Front

What are 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.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does air resistance affect falling objects?

Back

Air resistance, a type of friction, slows down the motion of falling objects, causing them to fall at different rates.

Front

What happens when two students pull on a rope with equal force?

Back

The rope remains motionless because the forces are balanced.

Front

What happens when one student pulls harder on a rope?

Back

The rope will accelerate in the direction of the stronger pull, indicating unbalanced forces.

Front

What is the effect of mass on gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force acting on it.

Front

What is the relationship between force and motion?

Back

A net force acting on an object causes it to accelerate, changing its speed or direction.

Front

What is an example of a balanced force in everyday life?

Back

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