Law of Inertia

Front

What is the Law of Inertia?

Back

An object in motion will stay in motion and an object at rest will remain at rest unless an unbalanced force acts on it.

Front

What is air resistance?

Back

Air resistance, also known as drag, is the force that opposes the motion of objects traveling through air.

What happens to a passenger in a car crash if they are not wearing a seatbelt?

Back

When the car stops, the passenger continues moving forward due to inertia.

Front

What causes objects in motion to eventually stop?

Back

An unbalanced force acts on them, such as friction or air resistance.

Front

What is inertia?

Back

Inertia is the property of an object that resists changes in its state of motion.

Front

How does mass relate to inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in motion more.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its speed or direction, affecting its motion.

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 unless acted upon by an unbalanced force.
