A. 0 N

B. 25 N

C. 50 N

D. 100 N

A. 2 N to the right

B. 2 N to the left

C. 8 N to the right

D. 8 N to the left

Question 5

**Which of the following is NOT an example of Newton's First Law in action?**

A. A book resting on a table.

B. A ball rolling on a frictionless surface.

C. A car accelerating when the gas pedal is pressed.

D. A satellite orbiting Earth in space.

Question 6

**a)** Define Newton's First Law of Motion and explain its significance in understanding the concept of inertia. [3]

**b)** A book is placed on a table. Identify the forces acting on the book and explain how Newton's First Law is applicable in this scenario. [2]

Question 7

**a)** Describe the relationship between force, mass, and acceleration as stated by Newton's Second Law of Motion. [2]

**b)** A car of mass 1000 kg accelerates from rest to 20 m/s in 10 seconds. Calculate the net force exerted on the car during this time. [3]

Question 8

**a)** State Newton's Third Law of Motion and provide a real-world example illustrating this law. [2]

**b)** In a tug-of-war game, if team A exerts a force of 500 N to the right, what force does team B exert and in which direction? [2]

Question 9

**a)** Define inertia and explain how it is related to Newton's First Law of Motion. [2]

**b) **A 5 kg object is at rest on a frictionless horizontal surface. If a horizontal force of 10 N is applied to the object, calculate its acceleration. [2]

**c)** How long will it take for the object to reach a speed of 20 m/s starting from rest? [3]

Question 10

**a) **Differentiate between weight and mass. [2]

**b)** If an object has a mass of 50 kg, calculate its weight on Earth. (Use g = 9.81 m/s^2 for acceleration due to gravity) [2]

**c) **How would the weight of the object change if it were taken to the moon where the acceleration due to gravity is approximately 1/6th of that on Earth? [3]
