Newton's Laws of Motion

What is the other name for Newton's First Law of Motion?

• Law of Inertia

• Principle of Gravity

• Law of Rest

• Newton's Third Law

State Newton's Second Law of Motion.

• F = ma

• F = 2ma

• F = a/m

• F = mv

According to Newton's Third Law of Motion, for every action, there is an equal and opposite ____________.

• opposite force

• opposite reaction

• equal reaction

• reaction

What is the SI unit of force?

• Newton (N)

• Joule

• Kilogram

• Meter

An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force. This statement is related to which law of motion?

• Newton's First Law of Motion

• Archimedes' Principle

• Newton's Third Law of Motion

• Newton's Second Law of Motion

What is the formula for calculating force based on Newton's Second Law of Motion?

• F = m^2a

• F = mv

• F = ma^2

• F = ma

Give an example of Newton's Third Law of Motion in everyday life.

• Swimming

• Jumping

• Walking

• Running

What is the acceleration of an object with a mass of 5 kg and a force of 20 N acting on it?

• 4 m/s^2

• 6 m/s^2

• 10 m/s^2

• 2 m/s^2

How does Newton's Second Law of Motion explain the relationship between force, mass, and acceleration?

• Newton's Second Law suggests that mass is irrelevant in determining acceleration

• According to Newton's Second Law, acceleration is directly proportional to force and mass

• Newton's Second Law states that force is inversely proportional to mass and acceleration

• Newton's Second Law of Motion explains that the force applied to an object is equal to the mass of the object multiplied by its acceleration.

Explain the concept of inertia in relation to Newton's First Law of Motion.

• Inertia is the same as momentum in physics.

• Inertia is the ability of objects to change their motion easily.

• Inertia is the resistance of an object to changes in its motion, as described by Newton's First Law.

• Inertia is the force that causes objects to move.
