Question 7 of 12

7. Question
What is a force?
- Any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction
- An acceleration of an object by an outside force
- a movement that is controlled by gravity
Correct

Incorrect

The correct answer should be, Any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction
Question 8 of 12

8. Question
What is the mathematical equation for Force?
- F = a/b
- F = ma
- A = f/m
Correct

Incorrect

The correct answer should be, F=ma
Question 9 of 12

9. Question
What is the 2nd law of Motion?
- The acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Thus, F = ma, where F is the net force acting on the object, m is the mass of the object and a is the acceleration of the object.
- When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body.
- When viewed in an inertial reference frame, an object either is at rest or moves at a constant velocity, unless acted upon by an external force.
Correct

Incorrect
