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 happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is gravity?

Back

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

Front

How does gravity affect a ping-pong ball?

Back

Gravity pulls the ping-pong ball down toward the ground, preventing it from floating up to the ceiling.

Front

Can you give an example of balanced forces in everyday life?

Back

An example of balanced forces is when two people pull on opposite ends of a rope with the same amount of force.

Front

Can you give an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when one person pulls harder than another in a game of tug of war.

Front

What is the role of air pressure in forces?

Back

Air pressure can affect how objects move through the air, such as how a balloon rises or a ping-pong ball floats.

Front

What is the direction of a force?

Back

The direction of a force is the way in which the force is applied, which can change the motion of an object.
