Balanced/Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal in size or direction, causing a change in motion of an object.

Front

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

Back

The object stays still or moves at a constant speed and direction.

Front

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

Back

The object accelerates, decelerates, or changes direction.

Front

Give an example of balanced forces.

Back

A boulder sitting at the top of a hill with no movement.

Front

Give an example of unbalanced forces.

Back

A car accelerating around a mountain curve.

Front

What must happen for an object to change its speed or direction?

Back

The forces acting on the object must be unbalanced.

Front

What is the effect of gravity on objects?

Back

Gravity is a force that pulls objects toward each other, affecting their motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How do balanced forces affect motion?

Back

Balanced forces do not change the motion of an object.
