The fundamental implications of inertia are:
1. Inertia is the natural tendency of an object to either remain at rest or continue in a linear motion at a constant velocity.
2. Objects will remain at rest until disturbed by unbalanced forces, and will continue their motion unless acted upon by other unbalanced forces.
3. Inertia implies that a force is not required to sustain an object's motion, but is needed to change its state of motion.
- Galileo conducted experiments rolling balls down inclined planes and concluded that an object in motion stays in motion unless acted upon by an external force like friction. This tendency of objects to resist changes in their motion is called inertia.
- Newton later formalized this as his first law of motion, stating that objects at rest stay at rest and objects in motion stay in motion with constant velocity unless acted upon by an unbalanced force.
- An object's inertia is determined by its mass, with more massive objects requiring greater forces to change their state of motion. Mass is a measure of the amount of matter in an object and is distinct from its weight, which is the gravitational force acting on it.

Newton's First Law states that objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. Friction and gravity are examples of forces that cause moving objects to eventually stop. Newton's Second Law states that force equals mass times acceleration (F=ma). Newton's Third Law says that for every action there is an equal and opposite reaction - when one object exerts a force on a second object, the second object exerts an equal force back on the first.

Newton's first law of motion, also known as the law of inertia, states that 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. Galileo was the first to discover and describe inertia, observing that objects resist changes to their motion due to their mass. Newton later formalized inertia as his first law of motion.
This document summarizes key concepts from a physics textbook chapter about motion and forces. It discusses Aristotle's early definitions of natural and violent motion. It then covers Galileo's ideas that challenged Aristotle, including that friction is needed to stop an object in motion, and that inertia causes objects to remain in motion without a force. Galileo provided evidence for these ideas through experiments with rolling balls on inclined planes. The document also discusses Newton's first law of motion formalizing the concept of inertia. It explains that mass is a measure of an object's inertia, and defines inertia and mass. Finally, it addresses how the idea of inertia refutes early arguments against Copernicus' theory of a moving Earth.

Newton's First Law of Motion, also known as the Law of Inertia, states that 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. It describes what would happen in a car crash if the driver is not wearing a seatbelt, with the driver continuing to move at the speed of the car and hitting the interior rather than being held by the seatbelt.
1) An unbalanced external force is needed to change the motion of an object. Galileo observed that objects in motion tend to stay in motion and objects at rest tend to stay at rest, unless an external force acts upon them.
2) Newton further studied Galileo's ideas and formulated his three laws of motion. Newton's first law formalizes the idea that objects resist changes to their motion.
3) Newton's second law states that the acceleration of an object is directly proportional to the net external force acting on it, and inversely proportional to its mass. It can be expressed as: Force = Mass × Acceleration.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. It explains that in all interactions, there is a pair of forces acting on two different objects. The document provides examples of this, including a person pushing on a wall, a bee flying, and a rocket launching. It notes that while the forces are equal, they do not cancel out or balance since they act on different objects that undergo motion.

The document discusses key concepts related to force and Newton's laws of motion. It defines force and describes balanced and unbalanced forces. It explains inertia, momentum, and Newton's three laws of motion. Key points include that an unbalanced force causes acceleration according to F=ma, and that for every action there is an equal and opposite reaction.

This document summarizes Newton's three laws of motion. It introduces concepts like force, mass, inertia, and equilibrium. Newton's first law states that an object remains at rest or in uniform motion unless acted upon by a net force. The second law relates the net force on an object to its acceleration. The third law states that for every action force there is an equal and opposite reaction force. Other topics covered include weight, friction, tension and applying the laws of motion to problems involving equilibrium.
Newton's third law states that for every action, there is an equal and opposite reaction. It means that in any interaction between two objects, there are always two forces of equal magnitude acting in opposite directions. Examples given are a person pushing on a refrigerator, which results in the refrigerator pushing back with an equal force, and a horse pulling on the ground while the ground pushes forward on the horse with the same amount of force.
Students will be able to explain inertia, relate it to mass, and provide examples involving inertia. Inertia is an object's tendency to resist changes in its motion - objects at rest will stay at rest and objects in motion will stay in motion unless acted on by an unbalanced outside force. An object's inertia is directly proportional to its mass - the more mass an object has, the greater its inertia. Examples of inertia include a coin on cardboard pulled quickly, a ladder on a stopping truck, and other situations involving objects in motion experiencing changes.
1. Forces can change the motion of objects by moving stationary objects, changing the speed or direction of moving objects, or deforming objects. Balanced forces do not change motion while unbalanced forces do.
2. Friction opposes the motion of objects over a surface. Galileo's experiments with inclined planes showed that the motion of objects depends on the balance of forces.
3. Newton's laws of motion state that objects remain at rest or in uniform motion unless acted upon by an unbalanced force, the acceleration of an object depends on the net force acting on it and the object's mass, and for every action there is an equal and opposite reaction.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. The document provides examples of this law, such as bumper cars pushing against each other with equal forces in opposite directions. It also explains that it can be difficult to identify the action-reaction pair when one object is much more massive than the other and does not noticeably move, such as the Earth when a person walks on it. The document asks the reader to think of additional examples of Newton's third law of motion.
The document discusses Newton's laws of motion, including the laws of inertia, acceleration, and interaction. It explains that Newton's third law states that for every action there is an equal and opposite reaction. Examples provided include a car exerting a force on the ground as it moves, which causes an equal reactive force from the ground pushing the car forward. When jumping on a trampoline, a downward force is exerted on the trampoline, with an equal upward reactive force propelling the person into the air.
- The document discusses Newton's three laws of motion through examples and explanations. Newton's first law states that an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. Newton's second law relates that the greater the force applied to an object, the greater its acceleration. Newton's third law states that for every action, there is an equal and opposite reaction.
Forces can be pushes or pulls that change the motion or shape of objects, though forces themselves cannot be seen. Gravity is a force of attraction between all objects with mass. Weight is the gravitational force of the Earth on an object, measured in newtons. Pressure is the amount of force applied over an area, calculated as force divided by area and measured in pascals.
The Laws of Motion, formulated by Sir Isaac Newton, stand as the cornerstone of classical mechanics, providing a fundamental framework for understanding the motion of objects. Introduced in Class 11 physics curriculum, these laws elucidate the relationship between the motion of an object and the forces acting upon it. Newton's First Law, often termed the Law of Inertia, sets the stage by describing the natural tendency of objects to remain at rest or in uniform motion unless influenced by external forces. The Second Law establishes a quantitative link, defining how the acceleration of an object is directly proportional to the net force applied and inversely proportional to its mass. Finally, the Third Law introduces the concept of action and reaction, emphasizing that every force exerted by one object is met with an equal and opposite force from another. As students delve into these laws, they uncover a comprehensive understanding of the principles governing the dynamics of the physical world.

Newton's three laws of motion describe the relationship between an object's motion and the forces acting upon it. The first law states that objects at rest will stay at rest and moving objects will keep moving unless acted on by an outside force. The second law relates the acceleration of an object to the net force acting on it and its mass. The third law states that for every action force there is an equal and opposite reaction force. These laws help explain phenomena in sports such as how starting blocks aid sprinting and how force generation allows football players to affect other players' motions.
Sir Isaac Newton discovered the three laws of motion in the late 1600s. Newton's First Law states that 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. Newton's Second Law states that the force on an object equals its mass times its acceleration. Newton's Third Law states that for every action, there is an equal and opposite reaction.
The document discusses Newton's three laws of motion. It begins by defining key terms like force, inertia, and acceleration. It then explains each of Newton's three laws: (1) an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force, (2) acceleration is directly proportional to force and inversely proportional to mass, and (3) for every action there is an equal and opposite reaction. Examples are provided to illustrate Newton's laws, such as how gravity causes free fall acceleration. Balanced and unbalanced forces are also distinguished.
Newton's first law of motion states that 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. It describes the tendency of objects to resist any change in their state of motion. The document provides explanations of examples that illustrate Newton's first law, such as blood rushing to the feet when an elevator abruptly stops, or a person flying off a skateboard when it hits a rock. Galileo refined the concept of inertia, which is an object's resistance to changes in its motion.
Newton's first law of motion states that 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. It describes the tendency of objects to resist any change in their state of motion. The document provides explanations of examples that illustrate Newton's first law, such as blood rushing to the feet when an elevator abruptly stops, or a person flying off a skateboard when it hits a rock and stops suddenly. Galileo refined the concept of inertia, which is an object's resistance to changes in its motion.
Newton's three laws of motion are:
1) Law of inertia - an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
2) Law of acceleration - the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.
3) Law of action-reaction - for every action, there is an equal and opposite reaction.
Newton's First Law of Motion: I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This we recognize as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia".
The Law of Inertia (The 3 Laws of Motion).pptRose Alba
What is the meaning of law of inertia?
The law of inertia states that an object or mass will remain either at rest or in motion in the same direction, unless acted upon by an unbalanced force. This also means that the more massive an object is, the more difficult it is to influence its velocity.
Sir Isaac Newton discovered the three laws of motion in the late 1600s. The laws describe how objects move and the forces that cause changes in motion. The first law states that objects at rest stay at rest and objects in motion stay in motion unless acted on by an unbalanced force. The second law states that force equals mass times acceleration. The third law states that for every action there is an equal and opposite reaction. Newton published his laws in his influential book "Philosophiae Naturalis Principia Mathematica". His laws remain fundamental principles in physics.
1. The document discusses frames of reference and how an object's motion depends on the chosen reference frame.
2. It gives examples of how the speed of a ball shot from a toy cannon on a moving skateboard or train depends on whether it is measured relative to the moving object or a stationary observer.
3. Key ideas are that an object can have different speeds depending on the reference frame used, and its total velocity is the sum of speeds relative to different frames of reference.
The document discusses inertia and frames of reference in motion. It explains that a running start allows athletes to throw or jump farther by increasing the velocity of the object being thrown or jumped. Velocity is the sum of the speeds of the body and limbs. Frames of reference are important because an object's speed depends on the observer's perspective.
- The document discusses Newton's laws of motion and the concepts of force, inertia, mass, and momentum.
- Newton's first law states that objects resist changes to their motion unless acted upon by an unbalanced force. His second law establishes a relationship between force, mass, and acceleration.
- Momentum is defined as the product of an object's mass and velocity, and Newton showed that a larger force is needed to stop an object with greater momentum according to his second law.
The document discusses Newton's Three Laws of Motion. It provides definitions and examples for each law:
1. Newton's First Law of Motion, also called the Law of Inertia, states that 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.
2. Newton's Second Law of Motion, also called the Law of Acceleration, states that the acceleration of an object depends on the net force acting on it and its mass, according to the formula Force = Mass x Acceleration.
3. Newton's Third Law of Motion states that for every action force there is an equal and opposite reaction

Class, today we will learn about inertia. We experience inertia in almost every day of our life
without realizing it. This is because the concept is quiet abstract to witness. Let us refresh our
brains on the chapter of forces by discussing these questions: A) If you are travelling in a
vehicle at a constant speed, what happens to your motion when the driver applies the brakes on
the vehicle? B) Imagine, on the same floor horizontally so, if you push a box of 4 kg, and
then push a fridge of 208 kg, which one of the objects will accelerates more than the other?
Why is this the case? (Assume you apply an equal amount of force in the two case.
Question A.
You will agree that before the application of the brakes on the
vehicle, you were also travelling with the same speed of the vehicle
in the same direction of the vehicle. The application of the brakes
applies a force on the vehicle and you. This force is the one that is
responsible to changes the initial speed of the vehicle and yours.
Hence the vehicle will decrease in speed, so will you. However, you
will still want to lean forward a little bit as the brakes are applied.
This is because you resist a change in motion brought about by the
force of brakes, as the results we say that you have inertia. This
implies that if it wasn’t for the brakes, then you would still be
travelling at that constant speed of the vehicle without having to lean
forward.
F (brakes)
When the brakes are
applied on the vehicle,
the car accelerates in
the opposite direction
of motion. Leaning
forward is an indication
that you still tend to
conserve your initial
motion before the
application of brakes.
Question B.
It becomes easier for you to push the 4 kg box across the floor
than it is to push a 208 kg fridge. This is due to a relatively less mass
of the box than the fridge. As such, the fridge has a greater tendency
to remain at rest, (not move) than the box. Thus, we say the fridge
has more inertia than the box. Class, by now we should have an idea
of what inertia is.

Inertia
Inertia is the natural tendency of an object to remain at rest or in the state of motion at a non-
changing velocity. The quantitative measure of this tendency equals the mass of that object.
“This implies that inertia is measured with the SI units of kilogram (kg)” (Cutnell, 2014, p.86).

To gain a better understanding of inertia, imagine you put your soccer ball on a horizontal level
ground. You would agree with me that the ball will remain on the ground at that point until
otherwise kicked. The ball has a tendency of remaining at rest until it is disturbed. This is
referred to as the Inertia of Rest. Consider another example where a box slide across a
frictionless floor. The box will sustain its motion (keep moving at a constant velocity) until it
is acted upon by another force. What will happen if the box cross over to a rough floor? It is
obvious that the box will decreases in velocity until it comes to rest. The box changes its state
of motion due to the presence of another force acting on it. The box would still be travelling at
the constant velocity if it wasn’t for the frictional force it experienced on that rough floor simply
because it has the tendency to reserve its state of motion called Inertia of motion.
Classify the following instances as the results of Inertia of Rest or Motion
1. A balloon will rise indefinitely in the absence of gravitational force
2. When you travel in a train and throw an apple vertically upwards, it returns back to
your hand irrespective of the train’s motion.
3. A relatively larger net force is required to change the velocity of a vehicle than of a
bicycle.
4. The swirling of tea in a cup continues even after the stirring is stopped.
5. If pulled quick enough, “a table cloth can be removed from underneath the plates
without disturbing them” (Halley, 1960, p.230).
1. In this case a gravitational force opposes the state of
motion of the balloon, hence in its absence the balloon would
rise indefinitely due to Inertia of Motion.

2. With the train moving at a particular velocity, the apple
also assumes an equal velocity of the train, that is an equal
speed and direction. Hence once the apple is thrown upwards,
it still travels horizontally as well as the results of Inertia of
Motion. The apple moves
horizontally.
3. A vehicle with a greater mass has a greater tendency to
remain at rest than a bicycle with a smaller mass. “The vehicle
requires more net force because of Inertia at Rest” (Cutnell,
2014, p.86).
Bicycle with less mass
Massive vehicle
4. The tea continues to swirl because of Inertia of Motion.
It only stops because it collides with the walls of the cup.
5. The plates will experience almost no external force if the
cloth is pulled quicker. Hence the plates will remain
undisturbed due to their Inertia of Rest.

from underneath the plates
Class did you know that Galileo Galileo used the concept of inertia to predict that the earth
could be in motion (moving)? “He also used inertia to explain why we do not feel the motion
of the earth and why objects falling on the surface of the earth move together with the earth”
(Verma, 1999, p.124).
DID YOU KNOW?

Class, from what you have learnt from our lesson today, what is the implication of Inertia?
Inertia implies that a force is not required to sustain a state of motion of an object, but it is
there to change the state of motion instead.
1. Inertia is the natural tendency of an object to either remain at rest or to continue
being in a linear motion at a constant velocity, that implies a constant speed in the
same direction.
2. Objects will remain at rest until they are disturbed by unbalanced forces.
3. Objects will continue with their state of motion unless otherwise acted upon by
unbalanced forces.
Home Activity 17 March 2017
1. Define the term Inertia.
2. Distinguish between Inertia of Rest and Inertia of Motion.
3. Classify the following as Inertia of Rest or Inertia of Motion.
3.1 When you jump off a moving train, you fall forward.
3.2 When our vehicle jerk off, we lean backwards.
3.3 Objects always fall back to the centre of the earth.
The end!
