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 with the same speed and in the same direction unless acted upon by an unbalanced 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

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in the motion of an object.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.

Front

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

Back

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