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 force pulls objects towards the Earth?

Back

Gravity is the force that pulls objects towards the Earth.

Front

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

Back

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

Front

What happens to a moving object when unbalanced forces act on it?

Back

A moving object will change its speed or direction when unbalanced forces act on it.

Front

Can you give 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

Can you give 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 gravity in our daily lives?

Back

Gravity keeps us grounded on Earth, causes objects to fall, and affects how we move.

Front

How do balanced forces affect motion?

Back

Balanced forces do not change the motion of an object; it will either stay still or keep moving at the same speed in the same direction.

Front

How do unbalanced forces affect motion?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.
