1. Only A
2. Only B
3. Both B and C
4. A, B and D

Which of the following situations describes an object with zero acceleration?

1. A car increasing its speed while moving downhill.
2. A bicycle moving at a steady speed on a flat road.
3. A ball thrown into the air and falling back down.
4. A train slowing down as it approaches a station.

Answer: (b) A bicycle moving at a steady speed on a flat road.

Two runners start from the same point. Runner A runs 100 m north, and Runner B runs 100 m east. What is true about their distances and displacements

1. Both have the same distance and displacement.
2. Both have different distances but the same displacement.
3. Both have the same distance but different displacements.
4. Both have different distances and displacements.

Answer: (c) Both have the same distance but different displacements.

Imagine you are observing a ball being dropped from the top of a tall building. As the ball falls, it gains speed due to gravity. However, there is a strong wind blowing sideways, causing the ball to drift slightly to the left while falling. Considering the effects of both gravity and wind, what combination of motions best describes the ball's movement before it touches the ground?

1. Translational and oscillatory motion
2. Translational and accelerated motion
3. Rotational and periodic motion
4. Circular and uniform motion

Answer: (b) Translational and accelerated motion

A cyclist rides in a circular path at a constant speed. Which statement best describes the motion of the cyclist?

1. The cyclist is not accelerating because the speed is constant.
2. The cyclist is accelerating because the direction of motion is changing.
3. The cyclist's motion is uniform since they maintain a constant speed.
4. The cyclist is decelerating as they ride in a circle.

Answer: (b) The cyclist is accelerating because the direction of motion is changing.

In which situation can you observe non-uniform motion that is not periodic? A. A runner sprinting at varying speeds on a track. B. A metronome ticking at a consistent tempo. C. A bicycle moving downhill with increasing speed. D. A pendulum swinging with the same timing for each swing.

1. Only A
2. Only A and B
3. Only B and C
4. A, B and D

Answer: (a) Only A

A graph depicts an object’s position over time. Initially, it rises sharply for 3 s, then drops rapidly for 2 s before moving horizontally for 5 s. What can be inferred about the object's motion?

1. The object is launched upwards, falls back down, and stays at a constant height.
2. The object is moving forward, then backward, and finally comes to a halt.
3. The object travels straight up and then rolls back down a slope.
4. The object is at rest for the entire duration.

Answer: (a) The object is launched upwards, falls back down, and stays at a constant height.

Consider a velocity-time graph of a roller coaster that starts from rest, what can be inferred about the total distance travelled during the first 10 seconds?

1. The distance is 30 m.
2. The distance is 60 m.
3. The distance is 15 m.
4. The distance is 45 m.

Answer: (d) The distance is 45 m.

In a velocity-time graph, what can be inferred about the object’s motion after 4 seconds?

1. The object is accelerating.
2. The object is at rest.
3. The object is moving at a constant velocity.
4. The object is decelerating.

Answer: (c) The object is moving at a constant velocity.

A position-time graph depicts an object’s movement. What can be concluded about the object's motion between 4 seconds and 6 seconds?

1. The object is moving at a constant speed.
2. The object is moving faster than before.
3. The object is stationary.
4. The object is moving backwards.

Answer: (d) The object is moving backwards.
