What is a balanced force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size and 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.

Example of balanced forces in real life?

Back

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

Example of unbalanced forces in real life?

Back

A soccer ball being kicked is an example of unbalanced forces; the force of the kick is greater than the opposing forces, causing the ball to move.

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.

Front

What is net force?

Back

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

Front

If two forces of 20 N and 30 N act in the same direction, what is the net force?

Back

The net force is 50 N in the direction of the forces.

Front

If two forces of 40 N and 40 N act in opposite directions, what is the net force?

Back

The net force is 0 N, resulting in balanced forces.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
