Friction always acts in the direction

to the motion of an object.

Multiple Select

Select all the statements that are true about air resistance.

• It is a type of friction due to air molecules.

• It acts upon objects as they travel through the air.

• It helps objects move faster through air.

• It is most noticeable for objects traveling at fast speeds.

How does drafting help reduce air resistance in competitive events, and where might similar effects be observed in nature?

Multiple Choice

Which of the following best describes the force of tension?

• A force that is transmitted through a string, rope, cable, or wire when it is pulled tight by forces acting from opposite ends.

• A force that pushes objects together when compressed.

• A force that acts only on objects with mass.

• A force that acts only at a distance.

Why does the force of gravity have more of an impact on holding our solar system together compared to holding the parts of an atom together?

Multiple Choice

Which of the following is true about vectors?

• A vector has both direction and magnitude.

• A vector only has magnitude.

• A vector only has direction.

• A vector is always represented as a straight line without an arrow.

Multiple Choice

Which of the following statements about force is correct?

• Force is a push or pull acting on an object.

• Force is measured in kilograms.

• Force is a scalar quantity.

• Force cannot be combined to predict motion.

Fill in the Blanks

The overall force acting on an object when all of the forces acting on it are combined is called the

force.
