Newton's First and Second 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.

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 inertia?

Back

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

Front

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

Back

Increasing the force applied to an object results in greater acceleration.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

The object begins moving in the direction of the net force.

Front

What is the relationship between mass and acceleration?

Back

If you increase the mass of an object, its acceleration decreases for a given force.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

A soccer ball remains at rest until a player kicks it.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, such as starting, stopping, or changing direction.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, making it harder to start or stop moving.
