Inertia

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What does it mean for an object to experience an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate or change its motion.

Front

Which object has more inertia: a bowling ball or a baseball?

Back

A bowling ball has more inertia than a baseball because it has greater mass.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia. This means heavier objects are harder to start or stop moving.

Front

What happens to a moving object when no unbalanced force acts on it?

Back

A moving object will continue moving at a constant speed in a straight line.

Front

True or False? An object's inertia is affected by its mass.

Back

True. An object's inertia increases with its mass.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia, as their bodies want to continue moving forward.

Front

What is the relationship between inertia and motion?

Back

Inertia is directly related to motion; it describes how an object will behave when forces are applied or not applied.

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 example of an unbalanced force?

Back

A swing moving back and forth is an example of an unbalanced force acting on it, causing it to change direction.
