What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth.

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 an object's motion?

Back

Balanced forces do not change an object's motion; it remains at rest or continues to move at a constant speed.

Front

How do unbalanced forces affect an object's motion?

Back

Unbalanced forces cause an object to accelerate, decelerate, or change direction.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the forces are combined.

Front

If two forces of 30N and 40N act in the same direction, what is the net force?

Back

The net force is 70N in the direction of the forces.

Front

If a 50N force acts to the right and a 20N force acts to the left, what is the net force?

Back

The net force is 30N to the right.

Front

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

Back

The object remains at rest.
