### QUESTION 6Which of the following is **NOT** an example of accelerated motion?- A. A swinging pendulum- B. Vertical component of projectile motion- C. Circular motion at constant speed- D. Horizontal component of projectile motion- E. Earth's motion about sun---Students are required to identify which option out of the choices given is not an example of accelerated motion. To elaborate on the given options:- **A. A swinging pendulum** - This option involves periodic motion where the object is constantly changing direction, implying acceleration.- **B. Vertical component of projectile motion** - The vertical motion of a projectile is influenced by the force of gravity leading to acceleration.- **C. Circular motion at constant speed** - Even though the speed is constant, the direction is constantly changing, indicating acceleration.- **D. Horizontal component of projectile motion** - This is an interesting option to consider. In the ideal case without air resistance, the horizontal component of projectile motion maintains a constant velocity, implying no acceleration.- **E. Earth's motion about sun** - This option involves the Earth moving in an elliptical orbit around the Sun, which is an example of centripetal acceleration.The correct answer would be **D. Horizontal component of projectile motion**, as it does not exhibit acceleration under ideal conditions (ignoring air resistance).---This question enables students to analyze scenarios involving different types of motion and helps them understand the conditions under which acceleration occurs. **Question 7: What is the difference between speed and velocity?**- **A.** Speed is the rate at which velocity changes.- **B.** There is no difference.- **C.** Speed is the magnitude of velocity; velocity is a vector and has both magnitude and direction.- **D.** Speed is change in displacement over time; velocity is change in distance over time.- **E.** Speed is the rate at which something moves, while velocity is the direction in which it moves.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
