Newton's Laws Flashcards
1
Q
What is Newton’s first law?
A
Every body continues in a state of rest or uniform motion in a straight line unless a net (external) force acts on it
2
Q
What is Newton’s second law?
A
The rate of change of momentum (acceleration) of a body is directly proportional to the net force acting on the body, and the momentum change takes place in the direction of the net force
F=ma

Q
What is Newton’s third law?
A
When object X exerts a force on object Y, object Y exerts a force of the same type that is equal in magnitude and opposite in direction on object X
The two forces ALWAYS act on differentobjects and they form an action-reaction pair.
