Q1-Science 8-LC2 by AMC

What law of motion state that a body will remain at rest or move at constant velocity unless acted upon by external net or unbalance force?

• Law of Interaction

• Law of Inertia

• Law of Gravity

• Law of Acceleration

How is acceleration related to force?

• When acceleration of an object is increasing, the net force acting on it is decreasing.

• When acceleration of an object is decreasing, the net force acting on it is increasing.

• Acceleration of an object is directly proportional to the net forces acting on it.

• Acceleration of an object is inversely proportional to the net forces acting on it.

What law of motion states that for every action there is always an equal and opposite reaction?

• Law of Interaction

• Law of Inertia

• Law of Gravity

• Law of Acceleration

When mass is constant, what happens to the acceleration of an object when the magnitude of the net force acting on it is increasing?

• It will remain the same.

• It will be divided into two.

• It will increase.

• It will decrease.

• Law of Interaction

• Law of Inertia

• Law of Gravity

• Law of Acceleration
