Quiz For Science

What is gravitational force?

• what pushes mass-containing objects toward contact force

• what pushes gravitational objects toward one another

• what pushes mass-containing objects toward one another

• what lifts mass-containing objects from the core of the earth

Answer explanation

Humans frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. Yet, all mass-bearing objects are pulled toward one another by gravity.

How does the operation of the universe depend on gravity?

• The moon is held in its orbit around Earth by gravity, as are the planets in their orbits around the sun.

• The core of the earth is held in its orbit around America by gravity, as are the planets in their orbits around the sun.

• The moon is held in its orbit around Earth by gravity, as are the planets in their orbits around the moon.

• The moon is held in its orbit around Earth by paper airplanes, as are the planets in their orbits around the sun.

Answer explanation

The universe wouldn't function without a force that stablizes it's components.

Differences between weight and mass:

• Weight: Doesn't change.

  Mass: Changes with location.

• Weight: Changes with loaction.

  Mass: Never changes.

• Weight: Measured using (kg).

  Mass: Measured using (N).

• Weight: Measured in size only.

  Mass: Measured in size and direction.

Differences between weigth and mass:

• Weight: Dolphins like it.

  Mass: Is a location.

• Weight: Amount of matter within an object.

  Mass: Force that acts on mass due to gravity.

• Weight: Is a scaler quantity.

  Mass: Is a vector quantity.

• Weight: Measured in (N).

  Mass: Measured in (kg).

Diferences between weight and mass:

• Weight: Oceans.

  Mass: Boats.

• Weight: Isn't measured in (kg).

  Mass: Isn't measured in (N).

• Weight: Force that acts on mass due to gravity.

  Mass: Amount of matter within an object.

• Weight: Isn't a scaler quantity.

  Mass: Isn't a vector quantity.

If mass is 75kg and gravity is 9.8kg what is weight?

• 735N

• 700N

• 999N

• 65.2N
