8th grade final science exam practice

what is mass?

• mass describes the amount of matter in an object.

• mass is how much something weights.

• mass is a gravitational force

• all of the above.

what is weight?

• is the amount of space that an object takes up or occupies.

• is a measure of the size of an object

• is a measure of the gravitational force on an object.

• anything that has mass and takes up space.

what is density?

• density is a measure of the amount of matter in a given volume

• is how much matter is around a space.

• density is the mass in a given object

How does weight differ from mass?

• weight is the push or shove of the moons orbit rather the mass is the gravity of the world.

• weight is a measure of the amount of matter in an object where as mass is a measure of the resistance to acceleration.

• weight is a measure of the force of gravity while mass is the amount of matter in a given volume.

• weight is a measure of the gravitational force on an object. While mass stays the same for an object even when increased or decreased, gravitational forces change the weight of an object.
