Newton’s Laws Flashcards
1.
When an object is at rest, the forces
acting upon it are
a. Balanced
2.
When an object accelerates, the forces
acting on it are
a. Unbalanced
3.
An object in motion stays in motion
until acted upon by an outside force
a. Newton’s First Law
4.
An object at rest stays at rest until
acted upon by an outside force
a. Newton’s First Law
5.
The tendency of an object to remain in
motion or at rest is called
a. Inertia
6.
Newton’s second law states that
a. Force equals mass times acceleration
(F=M*A).
7.
For every force, there is an equal and
opposite force
a. Newton’s third law
8.
Newton’s First Law is nicknamed
a. The law of inertia
9.
Newton’s third law is nicknamed
a. The law of action and reaction
10. If you push against a wall, the wall will
push back against you with
a. An equal and opposite force
11. A passenger in a car that suddenly
stops will
a. Continue moving forward
12. Force equals
a. Mass times acceleration
13. Mass equals
a. Force divided by acceleration
14. Acceleration equals
a. Force divided by mass
