Laws of motion Flashcards
1
Q
What is Newton’s First Law?
A
An object in motion will stay in motion, and an object at rest will stay at rest; unless acted upon by an unbalanced force.
2
Q
What is Newton’s Second Law?
A
A force applied to an object will cause the object to accelerate in the direction of the force
3
Q
What equation governs Newton’s Second Law?
A
F = m a
Force equals mass times acceleration
4
Q
What is Newton’s Third Law?
A
For every action there is an equal and opposite reaction.
