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 force that pulls us toward the Earth.

Front

What is an example of balanced forces?

Back

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

Front

What is an example of unbalanced forces?

Back

When a person pushes a swing, the force of the push is greater than the force of gravity, causing the swing 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 role does air pressure play in forces?

Back

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

Front

How does gravity affect falling objects?

Back

Gravity pulls objects toward the ground, causing them to fall unless another force acts on them.

Front

What is an example of a situation with unbalanced forces?

Back

In a tug of war, if one team pulls harder than the other, the rope moves toward the stronger team.
