Balance and Unbalance Forces

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. If the forces are balanced, the net force is 0 N.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object does not accelerate and remains at rest or continues to move at a constant speed.

Front

What is an example of a balanced force?

Back

An asteroid moving at a constant speed through space is an example of balanced forces.

Front

What is gravity?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

How do you determine the direction of net force?

Back

The direction of the net force is determined by the direction of the larger force when forces are unbalanced.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.

Front

If a box is pushed with 10 N to the right and 5 N to the left, what is the net force?

Back

The net force is 5 N to the right.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.
