• Aligned with National Education Policy 2020
• Helpful in getting NAAC accreditation
• CBSE, ICSE, and state boards aligned curricula
• Engaging simulations with easy-to-teach instructions

• Within this simulated setting, you'll explore Newton's laws of motion through interactive experimentation.
• Experiment modules simulate scenarios where Newton's first law (law of inertia), second law (F=ma), and third law (action and reaction) are demonstrated.
• Real-life scenarios are integrated into the simulation, allowing participants to apply Newton's laws to practical situations.
• Feedback mechanisms guide users through the experimentation process, reinforcing key concepts and principles.

• The interactive nature of the simulation offers a dynamic and immersive learning experience, fostering deeper comprehension of Newtonian mechanics.
• Through this interactive involvement, you'll confront real-life situations, presenting practical scenarios for experimentation within the virtual realm.

Description

Newton’s First Law of Motion It states that “a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.”

Newton’s Second Law of Motion Newton’s Second Law of Motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
F = ma

Where F is the force applied, m is the mass of the body, and a is the acceleration produced.

What will happen if a body is subjected to multiple forces at the same time?
Suppose a body is subjected to multiple forces at the same time. In that case, the acceleration produced is proportional to the vector sum (that is, the net force) of all the individual forces.

The Second Law can also be shown to relate the net force and the momentum p of the body:

Therefore, Newton’s Second Law also states that the net force acting on a body is equal to the rate of change of momentum of the body.

How does the momentum affect the net force?

The First Law of Motion indicates that when an unbalanced external force acts on an object, its velocity changes, i.e., the object is accelerated.
