Kinematics

Question 1

Newton’s First Law of Motion

Answer 1

Any object at rest of in uniform motion in a straight line will remain at rest or in motion unless an external force acts on it.

Inertia

Question 2

Newton’s Second Law of Motion

Answer 2

The acceleration of an object is dependent upon the net force applied to the object, as well as the object’s mass.

Inertia

Question 3

Newton’s Second Law’s Associated Formula

Answer 3

F = m × a
