Newton's first law of 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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What does inertia refer to in physics?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What happens to a soccer ball kicked in outer space?

Back

It will continue in motion with the same speed and direction due to the lack of unbalanced forces.

Front

What is an example of Newton's First Law in everyday life?

Back

A coffee cup spills when a car stops suddenly because the coffee continues to move forward due to inertia.

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 the relationship between force and motion according to Newton's First Law?

Back

An object will not change its motion unless a net force acts on it.

Front

What would happen to a ball rolling on a frictionless surface?

Back

It would keep rolling indefinitely in the same direction and at the same speed.

Front

What is the significance of the term 'at rest' in Newton's First Law?

Back

It indicates that an object will remain stationary unless acted upon by an unbalanced force.

Front

How does Newton's First Law apply to a passenger in a car that suddenly stops?

Back

The passenger continues to move forward due to inertia, which can cause injury without a seatbelt.
