Newton Three Laws Of Motion Flashcards
What is Newton’s First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force.
What is another name for Newton’s First Law of Motion?
The Law of Inertia.
What is Newton’s Second Law of Motion?
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
What is the formula for Newton’s Second Law of Motion?
F = ma (Force = mass x acceleration).
What is Newton’s Third Law of Motion?
For every action, there is an equal and opposite reaction.
Give an example of Newton’s Third Law of Motion.
When you jump off a boat, the boat moves in the opposite direction.
What is the SI unit of force?
Newton (N).
How do Newton’s laws of motion relate to each other?
The first law explains what happens when no force is acting, the second law explains what happens when a force is applied, and the third law explains the interaction between two objects.
What is the significance of Newton’s laws of motion?
They are fundamental principles that describe the relationship between the motion of an object and the forces acting on it.
Who is credited with defining the laws of motion?
Sir Isaac Newton.
