Newtons Laws

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.

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 Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a)

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

The object will maintain its current state of motion (either at rest or moving at a constant velocity).

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in the motion of an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)
