Pressure

The mass of the object

The strength of the gravitational field

The color of the object

The mass of the planet it is on

No, mass and weight are the same

Yes, because it still consists of matter

No, because mass is caused by gravity

Only if it is moving

It only happens between two solids

It always speeds things up

It can occur in liquids and gases too

It is a force that pulls objects toward the Earth

To reduce the amount of water used

To make the bathtub look better
