PMA1- Balanced and Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction. If forces are in opposite directions, subtract the smaller force from the larger force.

Front

If a force of 40 N is acting to the right and a force of 60 N is acting to the left, what is the net force?

Back

The net force is 20 N to the left.

Front

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

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the net force when two equal forces of 30 N act in opposite directions?

Back

The net force is 0 N, meaning the forces are balanced.

Front

If you push a box with a force of 25 N to the right and someone else pushes with 15 N to the left, what is the net force?

Back

The net force is 10 N to the right.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the effect of unbalanced forces on an object?

Back

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

Front

If a couch is pushed with 35 N to the right and 25 N to the right, what is the net force?

Back

The net force is 60 N to the right.
