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 a net external force.

Front

Define inertia.

Back

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

Front

What does Newton's Second Law of Motion state?

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 according to Newton's Second Law?

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

Give an example of Newton's First Law in everyday life.

Back

A cup of coffee spills when a car makes a sharp turn because the coffee's inertia keeps it moving in a straight line.

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 the equal and opposite force to the force of gravity acting on a person standing on the ground?

Back

The person exerts an upward force on the ground equal to the force of gravity acting on them.

Front

How does friction affect motion according to Newton's laws?

Back

Friction is a force that opposes motion, affecting the net force and thus the acceleration of an object.

Front

What is the significance of the net force in Newton's Second Law?

Back

The net force determines the direction and magnitude of an object's acceleration.
