• Electricity

• Friction

• Magnetism

• Motor

NGSS.MS-PS2-3

NGSS.MS-PS2-4

It is a force of attraction that acts on everything in the universe with mass.

• Electricity

• Gravity

• Friction

• Magnetic

NGSS.MS-ESS1-2

NGSS.MS-PS2-4

Gravity makes all objects attract one another.

• False

• True

Tags

NGSS.MS-PS2-4

Gravity can only be strong.

• False

• True

Tags

NGSS.HS-PS2-4

Gravity depends on the mass and the distance.

• False

• True

Tags

NGSS.MS-PS2-4

It is the measurement of how much gravitational force acts on an object.

• Mass

• Volume

• Weight

It is the force that puts up resistance or stops motion along an object’s surface.

• Electicity

• Friction

• Gravity

• Magnetism

For friction to occur, there has to be contact between the surfaces of two objects.

• False

• True

In friction the size of the objects and size of the surfaces are important.

• False

• True

If the surfaces are smoother, more friction is produced.

• False

• True
