Laws of Motion Flashcards
Newtonian Physics (8 cards)
1
Q
Who developed the laws of motion?
A
Sir Isaac Newton.
2
Q
What is Newton’s First Law of Motion?
A
An object at rest stays at rest, and an object in motion stays in motion unless acted on by a force (also called inertia).
3
Q
What is Newton’s Second Law of Motion?
A
Force = Mass × Acceleration (F = ma).
4
Q
What is Newton’s Third Law of Motion?
A
For every action, there is an equal and opposite reaction.
5
Q
What is inertia?
A
The resistance of an object to change its motion.
6
Q
What is acceleration?
A
The rate of change of velocity over time.
7
Q
What are examples of forces?
A
Gravity, friction, applied force, tension.
7
Q
What unit is force measured in?
A
Newtons (N).
