Balanced & Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object 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 the motion of an object.

Front

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

Back

An object will either stay still or move at a constant speed and direction.

Front

What happens to an object when unbalanced forces act on it?

Back

An object will accelerate, decelerate, or change direction.

Front

Example of balanced forces in everyday life?

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

Front

Example of unbalanced forces in everyday life?

Back

A marble rolling down a ramp is an example of unbalanced forces; gravity pulls it down while no opposing force is equal.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often causing unbalanced forces.

Front

How do balanced forces affect a moving car?

Back

If a car is moving at a constant speed in a straight line, the forces acting on it are balanced.

Front

What is the role of gravity in unbalanced forces?

Back

Gravity is a force that can create unbalanced forces, such as when an object falls.

Front

Can balanced forces change the shape of an object?

Back

Yes, balanced forces can change the shape of an object, like squeezing a sponge, but they do not change its motion.
