NGSS.MS-PS2-2

A quantity which has both magnitude and direction.

• Scalar quantity

• Vector Quantity

• Speed

• Velocity

It is the force between two surfaces in contact. It has a direction opposite to the motion and parallel to the surface.

• Tension

• Magnetic Field

• Friction

• Non-contact Force

It is the gravitational force exerted by the Earth on any object. It is measured in newton (N) because it is a kind of force.

• Weight

• Mass

• Gravity

• Contact force

A quantity which has only magnitude and is completely specified by a number and a unit.

• Vector

• Resultant Force

• Scalar Quantity

• Net Force

The point where the whole weight of a certain body can be considered concentrated.

• Point of Equilibrium

• Static Equilibrium

• Center of Gravity
