Balanced and unbalanced forces

Front

What are balanced forces?

Back

Forces that are equal in strength and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal in strength or direction, causing an object to move.

If two people push a box with different forces, what will happen?

Back

The box will move in the direction of the stronger force.

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant speed.

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate, change direction, or change speed.

Front

What happens when two equal forces act in opposite directions?

Back

They cancel each other out, resulting in balanced forces.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its state of motion.
