Net Force Practice

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when they are not equal in size or direction, causing a change in motion.

Front

If an airplane is sitting on the runway, are the forces acting on it balanced or unbalanced?

Back

Balanced.

Front

What happens to an object when the net force is zero?

Back

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

Front

If a marble rolls down a ramp, are the forces acting on it balanced or unbalanced?

Back

Unbalanced.

Front

What is an example of balanced forces in everyday life?

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

Front

What is an example of unbalanced forces in everyday life?

Back

Pushing a shopping cart forward while someone else pulls it backward creates unbalanced forces.

Front

How do you calculate net force when two forces act in the same direction?

Back

Add the magnitudes of the forces together.

Front

How do you calculate net force when two forces act in opposite directions?

Back

Subtract the smaller force from the larger force.
