Sample questions

1. What type of motion is described when an object moves in a straight line?

   1. Circular Motion
   2. Linear Motion
   3. Periodic Motion
   4. Rotational Motion
   Show answer

   Answer: B. Linear Motion

   Linear motion is when an object moves along a straight path. This can include movements such as a car travelling straight down a road.

2. Which of the following is NOT an example of circular motion?

   1. Earth orbiting the Sun
   2. A child on a swing
   3. A car turning a corner
   4. A rocket moving in a straight line
   Show answer

   Answer: D. A rocket moving in a straight line

   A rocket moving in a straight line is an example of linear motion, not circular motion.

3. Which of the following is an example of rotational motion?

   1. A dog running
   2. A wheel spinning
   3. A ball being thrown
   4. A train moving forward
   Show answer

   Answer: B. A wheel spinning

   A wheel spinning is an example of rotational motion as it rotates around its axis.

4. Which example illustrates non-uniform motion?

   1. A person walking at a constant pace
   2. A car decelerating at a traffic light
   3. A train traveling at 60 km/h
   4. A kite flying straight up
   Show answer

   Answer: B. A car decelerating at a traffic light

   A car decelerating at a traffic light represents non-uniform motion since its speed is changing.

5. Why is the trajectory of a projectile always curved?

   1. Due to air resistance
   2. Due to change in direction
   3. Due to constant speed
   4. Due to gravity
   Show answer

   Answer: D. Due to gravity

   The curved trajectory of a projectile is caused by the uniform downward acceleration due to gravity acting on it after it is projected.
