Balanced & Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, causing the object to move.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.

Front

What happens when forces are balanced?

Back

When forces are balanced, an object will remain at rest or continue to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, an object will accelerate, meaning it will speed up, slow down, or change direction.

Front

What is an example of balanced forces?

Back

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

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when a person pushes a shopping cart; the push causes the cart to move.

Front

What is the role of air pressure in forces?

Back

Air pressure can affect the movement of objects, such as keeping a ping-pong ball from flying up due to gravity.

Front

How does direction affect force?

Back

The direction of a force determines where an object will move; changing the direction of the force can change the object's path.

Front

What is an example of changing direction of force?

Back

An example is when a skateboarder turns; they change the direction of the force applied by leaning.
