Newtons 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

Define inertia in the context of Newton's First Law.

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 unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

Explain the concept of action-reaction forces as per Newton's Third Law of Motion.

Back

For every action, there is an equal and opposite reaction.

What is momentum and how is it calculated?

Back

Momentum is the product of an object's mass and its velocity (p=mv).

Front

How does mass affect the acceleration of an object according to Newton's Second Law?

Back

As mass increases, for a given force, the acceleration decreases.

Front

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

Back

The net force is the total force acting on an object, determining its acceleration.

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.
