To decide if an object is in motion or at rest, one must choose a reference point. If the object’s position changes relative to the reference point over time, it is in motion; if not, it is at rest.
The paragraph explains that an object’s motion or rest is relative to the chosen reference point. Deepa observed that passengers appeared at rest when considering the bus as the reference, but in motion when comparing them to external objects.
When an orange drops from a tree, it initially moves downward due to gravity, following a curved path called a parabola. Although it primarily moves straight down, air resistance and other factors can cause slight deviations in its trajectory.
Examples of linear motion in my surroundings include a car driving straight on a road, a train moving along its tracks, and a person walking directly to a destination. Each instance involves movement along a straight path without deviation.
Swings and merry-go-rounds do not exhibit linear motion. Instead, swings exhibit periodic motion as they swing back and forth, while merry-go-rounds demonstrate rotational motion as they spin around a central point, both involving circular paths.
A reference point is a fixed location or object used to determine the position or motion of another object. It provides a basis for measuring distance, direction, and movement, helping to describe the location of an object relative to it.
Trees prevent soil erosion by stabilizing soil with their roots, which anchor the soil and reduce runoff. Their canopy also slows rain impact, helping to maintain soil integrity and prevent erosion.
Deforestation disrupts the water cycle by reducing transpiration, leading to less moisture in the atmosphere. This can decrease rainfall, affect water availability, and contribute to drier conditions and reduced groundwater recharge.
Non-renewable resources are natural resources that cannot be replenished once used, such as fossil fuels (coal, oil, natural gas) and minerals. They are finite and deplete over time with consumption.
