Introduction to Mass and Weight Video

What is inertia?

• The amount of space an object occupies

• The speed at which an object moves

• The force that pulls objects towards the Earth

• An object's resistance to changes in motion

How is inertia measured?

• By the object's speed

• By the object's mass

• By the object's temperature

• By the object's volume

What is the unit of force?

• Kilogram

• Newton

• Second

• Meter

What does the weight of an object depend on?

• Its mass

• The force of gravity

• Its speed

• Its volume

How do you calculate the weight of an object?

• Weight = mass × speed

• Weight = mass × volume

• Weight = mass × acceleration due to gravity

• Weight = mass × temperature
