Newton's 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 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 force?

Back

Any push or pull on an object.

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 is the unit of force?

Back

Newton (N)

Front

What happens to a crumpled piece of paper and a flat sheet of paper when dropped?

Back

The crumpled paper hits the ground first due to less air resistance compared to the flat paper.

Front

What does it mean for an object to have constant velocity?

Back

It means the object is moving at a constant speed in a straight line.

Front

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

Back

As mass increases, acceleration decreases if the force remains constant.
