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.
