NGSS.HS-PS2-1

Resistance of a fluid against the forward movement of an object.

• Drag

• Friction

• Applied Force

• Air Resistance

Answer explanation

Air Resistance is a type of Drag, but drag is more accurate because it can apply to liquids or gases.

A force that opposes motion between two surfaces that are in contact

• Friction

• Drag

• Tension

• Applied Force

the motion of a body when only the force of gravity is acting on the body

• Free Fall

• Drag

• Gravity

• Acceleration

A measure of the force exerted on an object by a gravitational field.

• Weight

• Gravity

• Inertia

• Constant Velocity
