Sample Questions on Law of Inertia

Question 1: Why do Objects Slow Down?

Solution:

The slowing down of items was thought to be an inherent characteristic of the things prior to Newton and Galileo. Friction and gravity were unknown forces at the time. The frictional force resists an object’s motion, causing it to lose energy and hence slow down.

When we watch a toy car traveling on a concrete surface, for example, the speed of the automobile is governed by the friction between the road and the vehicle wheels. The wheel will meet with little resistance when the toy automobile is driven over a smooth surface. This will create a frictional hurdle, allowing the automobile to accelerate across the entire plain tile surface.

This is in stark contrast to when a vehicle toy is driving on a slick, gravel-filled terrain. The idea of change in the condition of rest or motion is defined by Newton’s first law of motion.

Question 2: What are the effects of External Force on the Motion of the Object?

Answer:

There are various effects of External Force on the Motion such as:

• It has the potential to alter the direction of motion.
• It has the potential to alter the body’s speed.
• It has the ability to modify the direction as well as the speed of motion.
• It has the ability to start or halt motion in a stationary body.
• It has the potential to alter the size and/or form of the body.

Question 2: What is Newton’s first law of motion?

Solution:

Newton’s first law of motion states that a body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.

Question 3: What is motion?

Solution:

The change in position of a body/object with regard to time is known as motion. Distance, displacement, speed, velocity, and acceleration are the characteristics used to characterize motion.

Question 4: What do you mean by force?

Solution:

A force is defined as the push or pull that affects or tends to modify the condition of rest or uniform motion (constant velocity) of a body, according to Newton’s first law of motion.

Question 5: What is inertia?

Solution:

A characteristic of matter that allows it to remain in its current condition of rest or uniform motion in a straight line until it is disrupted by an external force is called an inertia.

Law of Inertia is another name for the First Law of Motion given by Sir Isaac Newton. As Law of Inertia has been studied by various scholars, throughout the centuries, and it helped humanity to understand the various concepts of motion in a wide range of fields from aerospace to automobile design.

The origins of the Law of Inertia can be traced back to the ancient Greek philosophers such as Aristotle and Galileo, who first posited the idea of “natural motion.” But until Sir Isaac Newton redefined the Law of Inertia as the “first law of motion” in the 17^th century, it was not widely used by science scholars.

Their Law of Inertia is also called Newton’s First Law of Motion. In this article, we will dive deeper into the concept of the Law of Inertia and other related topics in good detail.
