Newton's Laws 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 at a constant velocity unless acted upon by a net external force.

What is an example of Newton's First Law of Motion?

Back

A soccer ball remains motionless until it is kicked by a player.

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 an example of Newton's Second Law of Motion?

Back

A heavier object requires more force to move than a lighter object.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an example of Newton's Third Law of Motion?

Back

When you sit on a chair, your body exerts a downward force on the chair, and the chair exerts an equal upward force on your body.

Front

What does the term 'inertia' mean?

Back

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

Front

What is the relationship between mass and inertia?

Back

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

Front

What is a reference point in motion?

Back

A reference point is a stationary object used to determine the position of a moving object.

Front

What is the significance of a net force?

Back

The net force is the overall force acting on an object, determining its acceleration.
