What is the first law of motion with example?

The motion of an airplane when the pilot changes the throttle setting of the engine is described by the first law. The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton’s first law.

Q. Are force pairs always equal?

According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction.

Q. What is the first law of motion class 9th?

The first law of motion is stated as: An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force. The tendency of undisturbed objects whether they are at rest or moving with uniform velocity is called inertia.

Q. What is meant by inertia?

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. Inertia comes from the Latin word, iners, meaning idle, sluggish.

Q. How do you explain the first law of motion?

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.

Q. What are the applications of first law of motion?

Newton’s first law of motion states that “An object at rest stays at rest, an object in motion stays in motion with same speed and direction unless acted by a force”. Some of the applications of this law are : (i) Consider the use of seat belts in a car.

Q. How can Newton’s first law can be derived from Newton’s second law?

Explanation: Newton’s First Law of Motion states that a body will stay at rest or continue its path with constant velocity unless an external force acts upon it. By definition, then, there is constant velocity (possibly constant zero velocity). Thus, it seems that Newton’s Second Law of Motion leads to the First Law.

Q. What would happen if inertia didn’t exist?

Originally Answered: What would happen if there was no inertia? Objects would stop moving as soon as there was no longer any force being applied to them. The Earth would stop spinning, light wouldn’t move, and particles would fall apart.
