FAQs on L2 - Newtons's Second (2nd) Law of Motion - Motion, Class 9, Science Video Lecture
| 1. What is Newton's Second Law of Motion? |  |
Ans. Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force applied on it and inversely proportional to its mass. This can be mathematically represented as F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
| 2. How does Newton's Second Law of Motion explain the motion of objects? | |
Ans. Newton's Second Law of Motion explains that the motion of objects depends on the net force acting on them and their mass. If a larger force is applied to an object with a smaller mass, it will experience a greater acceleration. On the other hand, if the same force is applied to an object with a larger mass, it will experience a smaller acceleration. This law helps determine how objects move and how their motion can be manipulated.
| 3. Can Newton's Second Law of Motion be applied to both linear and rotational motion? | |
Ans. Yes, Newton's Second Law of Motion can be applied to both linear and rotational motion. In linear motion, the law states that the force applied to an object will cause it to accelerate in the direction of the force. In rotational motion, the law states that the torque applied to an object will cause it to rotate with a certain angular acceleration. Therefore, the law is applicable to various types of motion.
| 4. What are some real-life examples that demonstrate Newton's Second Law of Motion? | |
Ans. There are several real-life examples that demonstrate Newton's Second Law of Motion. Some common examples include:
- Pushing a car: When you push a car, the force you apply causes it to accelerate in the direction of the force.
- Kicking a football: The force applied by your leg causes the football to accelerate and move in the direction of the kick.
- Throwing a baseball: The force exerted by your arm causes the baseball to accelerate and move towards the target.
| 5. How does Newton's Second Law of Motion relate to the concept of inertia? | |
Ans. Newton's Second Law of Motion is closely related to the concept of inertia. Inertia is the tendency of an object to resist changes in its motion. According to Newton's Second Law, the greater the mass of an object, the greater its inertia. This means that objects with more mass require larger forces to accelerate them compared to objects with less mass. Inertia can be thought of as a measure of how resistant an object is to changes in its motion, and Newton's Second Law helps quantify this relationship.

Newton's Second Law of Motion.
The royal king invites you to join the Grand Science Festival.
Newton's Second law states that the rate of change of momentum of an object is directly proportional to the unbalanced force in the direction of force.
Therefore, F is directly proportional to ma.
Force applied by Newton causes the rock to move only slightly.
Why don't you try to move the rock?
Force applied by the horse causes the rock to move a greater distance.
Newton applies less force, less acceleration is produced.
Horse applies more force, more acceleration is produced.
Hence, force is proportional to acceleration.
Mass of Newton is less, therefore applied force is less.
Mass of horse is more, therefore applied force is more.
Therefore, force is directly proportional to mass.
Force is directly proportional to mass.
Force is directly proportional to acceleration.
Hence, force is directly proportional to the product of mass and acceleration.
The End.
