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 a net external force.

Front

What does inertia refer to in the context of motion?

Back

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

Front

How does mass affect gravitational pull?

Back

Objects with greater mass exert a stronger gravitational pull.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it rubs against another object.

Front

What happens to a hockey puck on a frictionless surface?

Back

It will continue to slide indefinitely without slowing down, as there are no opposing forces acting on it.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is an example of an object at rest?

Back

A book lying on a table.

Front

What is an example of an object in motion?

Back

A car driving down a straight road.

Front

What is the significance of a net external force?

Back

A net external force is required to change the motion of an object, either to start moving, stop, or change direction.

Front

What is the Law of Inertia?

Back

The Law of Inertia is another name for Newton's First Law of Motion.
