Mass and Weight Measurement

What is the definition of mass?

• The force exerted by gravity on an object.

• The amount of matter in an object.

• The weight of an object on Earth.

• The gravitational field strength.

Which of the following is a vector quantity?

• Mass

• Weight

• Both Mass and Weight

• Neither Mass nor Weight

What is the SI unit for mass?

• Newton (N)

• Meter (m)

• Kilogram (kg)

• Second (s)

What equation represents the relationship between weight and mass?

• Weight = Mass / Gravitational acceleration

• Weight = Mass * Gravitational acceleration

• Weight = Gravitational acceleration / Mass

• Weight = Mass + Gravitational acceleration

Why is understanding the distinction between mass and weight important in engineering?

• It helps measure time more accurately.

• It affects the stability, durability, and safety of structures.

• It determines the speed of vehicles.

• It is not important in engineering.
