Balanced and Unbalanced Forces

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 the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What does net force mean?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

What happens to an object when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant speed.

Front

What is the net force of an object with 50 N to the right and 50 N to the left?

Back

The net force is 0 N, indicating balanced forces.

Front

If a car is moving at a constant speed, what type of force is acting on it?

Back

Balanced forces are acting on the car, as there is no change in its motion.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes both speed and direction.

Front

What is an example of unbalanced forces in everyday life?

Back

A person pushing a shopping cart that is moving forward; if they push harder, the cart accelerates.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.

Front

What is an example of balanced forces?

Back

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