Question 1: What does Newton’s first law of motion state?

A) An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

B) For every action, there is an equal and opposite reaction.

C) The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object’s mass.

Correct Answer: A) An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Question 2: Which law explains why we need to wear seat belts?

A) Law of Conservation of Momentum

B) Newton’s first law of motion

C) Boyle’s law

Correct Answer: B) Newton’s first law of motion

Question 3: What does the law of conservation of energy state?

A) Energy cannot be created or destroyed, only transformed from one form to another.

B) The total energy of an isolated system remains constant over time.

C) Both A and B

Correct Answer: C) Both A and B

Question 4: What is Boyle’s law concerning the properties of gases?

A) At constant temperature, the volume of a fixed amount of gas is inversely proportional to the pressure.

B) At constant pressure, the volume of a fixed amount of gas is directly proportional to its temperature in Kelvin.

C) The pressure of a gas is directly proportional to its temperature in Kelvin at constant volume.

Correct Answer: A) At constant temperature, the volume of a fixed amount of gas is inversely proportional to the pressure.

Question 5: What does Charles’s law state about gases?

A) The volume of a gas is directly proportional to the number of moles of gas at constant temperature and pressure.

B) At constant pressure, the volume of a fixed amount of gas is directly proportional to its temperature in Kelvin.

C) The pressure of a gas is directly proportional to its temperature in Kelvin at constant volume.

Correct Answer: B) At constant pressure, the volume of a fixed amount of gas is directly proportional to its temperature in Kelvin.

Question 6: What is the principle behind Archimedes’ principle?

A) When a body is fully or partially submerged in a fluid, it experiences an upward force equal to the weight of the fluid displaced by the body.

B) The buoyant force on an object in fluid is equal to the weight of the fluid displaced by the object.

C) Both A and B

Correct Answer: C) Both A and B

Question 7: According to Ohm’s law, what is the relationship between voltage (V), current (I), and resistance (R)?

A) V = I / R

B) The entropy of any isolated system always increases.

C) Both A and B

Correct Answer: C) Both A and B

Question 9: Kepler’s first law states that the orbit of a planet is an ellipse with the Sun at one of the two foci. What is this law commonly known as?

A) The law of orbits

B) The law of areas

C) The law of harmonies

Correct Answer: A) The law of orbits

Question 10: What does Hooke’s law state?

A) The force needed to extend or compress a spring by some distance is proportional to that distance.

B) The potential energy stored in a spring is proportional to the square of the distance it is stretched.

C) Both A and B

Correct Answer: C) Both A and B
