Balanced & Unbalanced Forces

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

Which has more inertia: a feather or a hammer?

Back

A hammer has more inertia than a feather because it has greater mass.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens when equal forces act on an object in opposite directions?

Back

The object remains at rest or continues to move at a constant velocity; it does not accelerate.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to accelerate, change direction, or change shape.

Front

If a force of 5 N is applied to a box with a friction force of 5 N in the opposite direction, what will happen?

Back

The box will not move because the forces are balanced.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force remains constant.
