Which of the following statements is true regarding force?

• Force is a scalar quantity

• Force is measured in joules (J)

• Force is a vector quantity.

• Force is not related to motion.

Which of the following statements correctly distinguishes between internal and external forces in a system?

• Internal forces are interactions between objects outside the body, while external forces are interactions within the body.

• Internal forces do not affect the motion of the system, while external forces do.
• Internal forces are always attractive, while external forces are always repulsive.
• Internal forces are interactions between objects within the body, while external forces are interactions from the surroundings.

In a force system, what is the resultant force when two forces act along the same line in the same direction?

• The resultant force is the difference of the two forces.
• The resultant force is zero.
• The resultant force is the average of the two forces.
• The resultant force is the sum of the two forces.

In a force system, if two forces of equal magnitude act in opposite directions, what is the net force on the object?

• The net force is twice the magnitude of one of the forces.

• The net force is the sum of the magnitudes of the two forces.

• The net force is zero

• The net force cause the object to move in a circular path

In a linear force system, if two forces of 8 N and 12 N act in the same direction, what is the resultant force?

• 4 N

• 8 N

• 12 N

• 20 N

What type of force is responsible for supporting the weight of a person landing from a jump?

• Tensile force

• Compression force

• Shear force

• Torsional force

When performing a stretching exercise, which type of force is applied to your muscles?

• Tensile force
• Torsional force

• Shear force
• Compression force

According to Newton's Second Law of Motion, how is acceleration related to force and mass?

• Acceleration = Force / Mass

• Acceleration = Force X Mass

• Acceleration = Mass / Force

• Acceleration = Force + Mass
