Balanced and Unbalanced Forces Flashcard

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal in size and opposite in direction, causing a change in an object's motion.

Front

Example of balanced forces?

Back

A book resting on a table, where the force of gravity is balanced by the upward force from the table.

Front

Example of unbalanced forces?

Back

A car accelerating forward while the brakes are applied.

Front

What is net force?

Back

The overall force acting on an object, calculated by combining all individual forces.

Front

What happens when net force is zero?

Back

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

Front

What is the direction of motion when net force is applied?

Back

In the direction of the net force.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object's motion to change, either speeding it up, slowing it down, or changing its direction.

Front

What is an example of a situation with unbalanced forces?

Back

A soccer ball being kicked, where the force of the kick is greater than the opposing forces.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the greater the force needed to change its motion.
