Balanced & Unbalanced Forces

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, causing a change in motion.

Front

How does changing the direction of a force affect motion?

Back

Changing the direction of a force can change the direction of an object's motion.

Front

What role does gravity play in motion?

Back

Gravity is a force that pulls objects toward the Earth, affecting their motion and preventing them from floating away.

Front

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

Back

An object at rest will remain at rest when balanced forces act on it.

Front

What is the effect of unbalanced forces on a stationary object?

Back

Unbalanced forces will cause a stationary object to start moving.

Front

Why is it important to consider the direction of forces?

Back

The direction of forces determines the resulting motion of an object, including whether it will accelerate, decelerate, or change direction.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table, where the force of gravity is balanced by the normal force from the table.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is a person pushing a shopping cart; if the push is stronger than friction, the cart will move.

Front

How can the strength of a force be measured?

Back

The strength of a force can be measured in newtons (N), which quantify the amount of force applied.
