Newton's Laws of Motion Quiz

According to Newton's first law of motion, an object at rest will remain at rest and an object in motion will continue in motion with constant velocity, unless acted upon by a ________.

• net force

• acceleration

• friction

• gravity

What is the formula for Newton's second law of motion?

• Vf = Vi + at

• Fnet = m/a

• D = Vi t + (1/2)at^2

• Fnet = ma

According to Newton's third law of motion, for every action force, there is an equal and opposite ________ force.

• friction

• normal

• equilibrium

• reaction

What is the SI unit of force?

• Second

• Meter

• Newton

• Kilogram

Which law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass?

• The Law of Inertia

• Newton's second law of motion

• Newton's third law of motion

• Newton's first law of motion

What is the formula for calculating the net force?

• net force = mass - acceleration

• net force = mass + acceleration

• net force = mass x acceleration

• net force = mass / acceleration

Which law of motion explains why a rocket moves forward when gases are expelled out of its engines?

• Newton's first law of motion

• Newton's third law of motion

• Einstein's theory of relativity

• Newton's second law of motion

What is the relationship between the net force and acceleration?

• Net Force and acceleration are directly proportional.

• Acceleration causes net force.

• Net Force has no effect on acceleration.

• Net Force and acceleration are inversely proportional.

Which of the following statements accurately distinguishes between kinematics and kinetics in the study of motion?

• Kinematics and kinetics are interchangeable terms used to describe the study of motion in physics.

• Kinematics focuses on describing motion, while kinetics focuses on analyzing the forces causing that motion.

• Kinematics studies the effects of forces on motion, while kinetics describes the mathematical equations of motion.

• Kinematics deals with the relationship between mass and motion, while kinetics investigates the time-dependent aspects of motion.
