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 inertia?

Back

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

Front

How does an unbalanced force affect an object at rest?

Back

An unbalanced force will cause an object at rest to start moving.

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 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 the formula for calculating force?

Back

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

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 in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

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

Back

As mass increases, acceleration decreases for a given force.
