Chap 4 and 5

Question 1

Newton’s first law

Answer 1

statement

- velocity is constant, and so acceleration is zero.

Question 2

Inertia

Answer 2

The natural tendency of an object to remain at rest or in motion at a constant velocity.

As a result of inertial, we have newton’s first law. When an object is accelerating is no longer in its natural state

Question 3

Newton’s 3rd law implications

Answer 3

• when action and reaction act on separate objects, each object accelerates separately.
• If on the same system, the forces are internal forces and they cancel each other out.
