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 two forces acting on an object are not equal, causing the object to move in the direction of the greater force.

Front

Give an example of a balanced force.

Back

A boy standing still is an example of balanced forces acting on him.

Front

Give an example of an unbalanced force.

Back

A car accelerating forward when the driver presses the gas pedal is an example of an unbalanced force.

Front

How do balanced forces affect the motion of an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

How do unbalanced forces affect the motion of an object?

Back

Unbalanced forces cause an object to accelerate, decelerate, or change direction.

Front

What happens to an object when equal forces act on it from opposite directions?

Back

The object will not move; it remains in its current state.

Front

What is the net force when two equal forces act in opposite directions?

Back

The net force is zero.

Front

If a 10 N force is applied to the right and a 5 N force is applied to the left, what is the net force?

Back

The net force is 5 N to the right.

Front

What is inertia?

Back

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