`\large\sf{\underline{Required \: Answer: }}`

1. An object can experience eighty-nine or more forces and not accelerate.

True

2. If an object is at rest then there must be no forces acting upon the object.

True

• It means that the net force acting on the object is zero.

3. The weight of an object is equal to the force of the gravity acting upon the object.

True

• weight of an object may be defined as mass times gravity.
• W = mg

4. Force can be measured in kilograms or Newtons depending upon the system of measurement (metric or otherwise)

False

• Force can be expressed in newtons in the metric system. Since kilogram is a unit of mass ,so force cannot be measured in kilogram.

5. The mass of an object is dependent upon the value of the acceleration of gravity.

True

6. Force is a vector quantity. There is always a direction associated with it.

True

• Since force has both magnitude and direction therefore it is a vector quantity.
