● The Gravitational Gauntlet Lab

Topic:Mass, weight

and gravity

Essential question: What is the

difference between mass and weight

Multiple Choice

Mass is ....

• The amount of matter in an object

• The amount of force of gravity on an object

• The volume of an object

Using a balance

Multiple Choice

Mass ....

• changes depending on location

• stays the same everywhere

Multiple Choice

Weight is .....

• the volume of an object

• the amount of matter in an object

• the force applied by the mass

Multiple Choice

Weight is depended on ...

• volume

• gravity

• speed of an object

Multiple Choice

Mass can never be "a zero" while weight can be a zero if there is no gravity.

• True

• False

Multiple Choice

Weight depends on _______, but they are _________.

• mass.... the same

• mass....... not the same

Multiple Choice

Mass never changes.

• True

• False

Gravity- every object in the universe
exerts a force on every other object.

The amount of gravitational force between
objects depends mass and distance

Gravity accelerates everything toward the
earth at 9.8m/s2

How do I calculate Weight?

Weight = Mass x gravity

Weight = 35 kg x 9.8m/s

Weight= Newtons

An astronaut weighs 480 Newtons on
Earth. The moon's gravitational pull
is 1/6 the gravitational pull of the
Earth.

Would the astronaut have the same
mass and weight on the Earth and
moon?
