Newton's Second Law Quiz

What does Newton's First Law of Motion state?

• An object will remain at rest or in uniform motion unless acted upon by a net force.

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is directly proportional to the net force acting on it.

• Force is equal to mass times acceleration.

What is the equation that summarizes Newton's Second Law?

• F = ma

• E = mc^2

• P = mv

• W = Fd

What does the equation F = ma allow us to calculate?

• The speed of an object

• The force applied to an object, its mass, and its acceleration

• The distance traveled by an object

• The energy of an object

What is the SI unit of force derived from Newton's Second Law?

• Joule

• Watt

• Newton

• Pascal

What is required to achieve the same acceleration for heavier objects compared to lighter objects?

• No force

• Less force

• The same amount of force

• Greater force

How can Newton's Second Law be rephrased?

• Force is directly proportional to mass and inversely proportional to acceleration.

• Force is directly proportional to acceleration and inversely proportional to mass.

• Acceleration is directly proportional to force and inversely proportional to mass.

• Acceleration is directly proportional to mass and inversely proportional to force.

What is the net force acting on an object?

• The force of gravity on the object

• The difference between the applied force and friction

• The force applied by a single source

• The sum of all the forces acting on the object

What tool is used to represent all the forces acting on an object?

• A free body diagram

• A pie chart

• A histogram

• A bar graph

How can forces be split for calculations?

• Into mass and acceleration components

• Into scalar and vector components

• Into x and y components

• Into positive and negative components

What can Newton's Second Law be used to calculate in astronomy?

• The temperature of planets

• The masses of faraway celestial objects

• The distance between stars

• The speed of light
