Forces Quiz

What is the force that opposes the motion of an object when it is in contact with another object?

• friction

• gravity

• inertia

• momentum

What are the two types of friction?

• Hard friction and soft friction

• Fast friction and slow friction

• Smooth friction and rough friction

• Static friction and kinetic friction

What factors affect the force of friction?

• Distance between the surfaces and the time of day

• Nature of the surfaces and force pressing the surfaces together

• Color of the surfaces and temperature of the environment

• Weight of the object and its shape

What is the difference between mass and weight?

• Mass is measured in pounds, while weight is measured in kilograms

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass and weight are the same thing

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object

What is the unit of force in the International System of Units (SI)?

• joule (J)

• meter (m)

• newton (N)

What is the net force acting on an object when two forces are acting in the same direction?

• The net force is zero

• The net force is the average of the two forces

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

• The net force is the difference of the two forces
