Which of the following forces is responsible for making a car stop when the brakes are applied?

• Friction

• Gravity

• Tension

• Air resistance

Which statement is true according to Newton's Second Law of Motion?

• The mass of an object increases as the force applied increases

• The acceleration of an object is directly proportional to the force and inversely proportional to its mass

• The mass of an object does not affect the force applied to it

• A force applied to an object has no effect on its motion
