Newton's First Law - Conceptual Physics Part 2

Open Ended

Why is Newton's first law also called the law of inertia, and what is its significance in understanding motion?

Multiple Choice

According to Newton's law of inertia, what will happen to an object at rest if no force acts upon it?

• It will start moving on its own

• It will remain at rest

• It will accelerate

• It will change direction

Multiple Choice

Which of the following best describes Newton's Law of Inertia as illustrated by the tablecloth trick?

• Objects at rest tend to remain at rest unless acted upon by an external force.

• Objects in motion tend to stop immediately when a force is applied.

• Objects at rest will always start moving on their own.

• Objects in motion will always change direction without a force.

Open Ended

Explain how Newton's Law of Inertia applies to both objects at rest and objects in motion, using examples from the slides.

Multiple Select

Which of the following scenarios demonstrates the effect of friction on inertia?

• A hockey puck sliding on a city street comes to rest.

• A puck sliding on an air table moves with no apparent loss in speed.

• A ball dropped from a height falls straight down.

• A car parked on a hill remains stationary.

Fill in the Blank

The law of inertia provides a completely different way of viewing motion from the ___.

Open Ended

A force of gravity between the sun and its planets holds the planets in orbit around the sun. If that force of gravity suddenly disappeared, in what kind of path would the planets move?

Fill in the Blank

According to Newton's Law of Inertia, if the force of gravity disappeared, each planet would move in a ___ line at constant speed.

Open Ended

What is Newton’s first law of motion?

Multiple Select

Select all statements that are true about inertia and mass.

• Mass is a measure of inertia.

• Objects with more mass require more force to change their motion.

• Inertia is unrelated to the amount of material in an object.

• An object with less mass has less inertia.

Fill in the Blank

The amount of inertia an object has depends on its ___.

Multiple Choice

Which of the following statements best describes the relationship between mass and inertia?

• The more mass an object has, the greater its inertia.

• The less mass an object has, the greater its inertia.

• Mass and inertia are not related.

• Inertia only depends on the shape of the object.

Why does a can filled with sand move less than an empty can when kicked with the same amount of force?

Multiple Choice

Which of the following statements correctly distinguishes between mass and volume?

• Mass is measured in kilograms, while volume is measured in cubic units such as centimeters or liters.

• Mass is measured in liters, while volume is measured in kilograms.

• Both mass and volume are measured in kilograms.

• Mass and volume are both measured in liters.

Multiple Choice

Which has more mass, a feather pillow or a common automobile battery?

• A feather pillow

• A common automobile battery

• Both have the same mass

• It depends on their size

Open Ended

Explain the difference between mass and weight, and why mass is considered more fundamental than weight.

Fill in the Blank

The mass of a stone remains the same whether it is on Earth, the moon, or in outer space. However, its ___ would be different in these locations.

Open Ended

Why is it just as difficult to shake a stone in its weightless state in space as it is in its weighted state on Earth?

Multiple Select

Select all the correct statements about mass and inertia.

• Mass is a property of an object that does not depend on its location.

• The inertia of an object is directly related to its mass.

• The force required to shake an object changes depending on its location.

• Mass and inertia are independent of each other.

Multiple Choice

Which of the following best describes the relationship between mass and inertia?

• Mass is a measure of inertia, or the resistance of an object to changes in its state of motion.

• Mass is the force of gravity on an object.

• Mass and inertia are unrelated properties.

• Inertia is the force that acts on mass.

Open Ended

Explain how mass and weight are related, and why they are not considered equal to each other.

Fill in the Blank

The SI unit of force is the ___.

Multiple Select

Select all statements that are true about the relationship between mass, weight, and location.

• At Earth's surface, 1 kilogram weighs 10 newtons.

• Away from Earth's surface, the same mass weighs less due to lower gravity.

• Mass and weight are always equal.

• Weight depends on the gravitational pull at a location.

Open Ended

Does a 2-kilogram bunch of bananas have twice as much inertia, mass, volume, and weight as a 1-kilogram loaf of bread when weighed in the same location? Explain your reasoning.

Open Ended

Reflecting on Newton's law of inertia, how do you think this principle applies to everyday situations you have observed or experienced?

Multiple Choice

How does Newton's first law, also known as the law of inertia, relate to Galileo's idea about forces and motion?

• It states that a force is always needed to keep an object moving.

• It is a restatement that a force is not needed to keep an object moving.

• It says objects at rest will always start moving on their own.

• It claims that motion is impossible without gravity.
