Questions and Answers

According to Newton's laws of motion, what happens to a body that is not acted upon by a force?

  • It remains at rest
  • It moves at a constant speed in a straight line (correct)
  • It changes direction
  • It accelerates

What did Isaac Newton use his three laws of motion to investigate and explain?

  • The motion of celestial bodies
  • The motion of electromagnetic waves
  • The motion of physical objects and systems (correct)
  • The motion of subatomic particles

According to Newton's laws of motion, what is the relationship between a body's acceleration, mass, and net force?

  • Acceleration is equal to mass multiplied by net force
  • Mass is equal to acceleration multiplied by net force
  • Acceleration is equal to net force divided by mass (correct)
  • Net force is equal to acceleration multiplied by mass

Flashcards

Newton's First Law

A body remains at rest or moves at a constant speed in a straight line unless acted upon by a force.

Newton's Laws Application

Newton used his three laws of motion to investigate and explain the motion of physical objects and systems.

Newton's Second Law

Acceleration is directly proportional to net force and inversely proportional to mass (F=ma).

Newton's Third Law

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

Study Notes

Newton's Laws of Motion

  • A body that is not acted upon by a force remains at rest or continues to move with a constant velocity.
  • Isaac Newton used his three laws of motion to investigate and explain the motion of objects on Earth and in the universe.

Newton's Second Law of Motion

  • There is a direct relationship between a body's acceleration, mass, and net force: acceleration is directly proportional to net force and inversely proportional to mass.

Newton's Third Law of Motion

  • The forces exerted by two bodies on each other are equal in magnitude and opposite in direction.

History of Newton's Laws of Motion

  • Newton's laws of motion were first stated in the late 17th century.

Fundamental Interactions

  • The strongest fundamental interaction is the strong nuclear force.
  • The weakest fundamental interaction is gravity.

Gravity

  • Gravity has no significant influence at the atomic and subatomic scale.
  • Gravity determines the motion of planets, stars, and galaxies.
  • Gravity plays a crucial biological function in maintaining the structure and function of living organisms, particularly in the case of plants and animals.
