Newton's Laws and Related Concepts Quiz

What does Newton's Second Law primarily describe?

• The relationship between force, mass, and acceleration
• The conservation of energy
• The law of inertia
• The principle of action-reaction

According to Newton's Second Law, how does the acceleration of an object change if the net force applied to it is doubled while its mass remains constant?

• It doubles
• It halves
• It remains the same
• It becomes four times greater

Which of the following correctly expresses Newton's Second Law mathematically?

• F = ma
• F = m/a
• F = a/m
• F = m²a

What is the definition of inertia?

• The tendency of an object to resist changes in velocity
• The force that causes objects to fall towards Earth
• The friction between two surfaces
• The energy possessed by a moving object

Which of Newton's laws is also known as the law of inertia?

• First law
• Second law
• Third law
• Fourth law

In the example with the car and the red block, why does the red block continue to move forward?

• It does not experience the stopping force
• It has more mass than the car
• It has less friction
• It has a greater initial velocity

Which statement about inertia is correct?

• Inertia is a force
• Inertia is the object's response to a change in motion
• Inertia only applies to stationary objects
• Inertia is directly proportional to acceleration

What is viscosity?

• A measure of the resistance of a liquid to flow
• The speed at which a liquid moves
• The density of a liquid
• The temperature of a liquid

How does temperature generally affect the viscosity of a liquid?

• Viscosity increases as temperature decreases
• Viscosity decreases as temperature decreases
• Temperature has no effect on viscosity
• Viscosity is independent of temperature

Which of the following factors does NOT affect viscosity?

• The color of the liquid
• The size of particles
• The shape of particles
• Intermolecular forces
