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.
No, using paper-like materials for cooking utensils is impractical because they cannot withstand high temperatures, moisture, or repeated use. They would disintegrate, burn, or lose strength, making them unsuitable for cooking purposes.
A cloth tumbler cannot be used to store water because cloth is porous, allowing water to seep through. It lacks the necessary waterproof properties to hold liquids, making it unsuitable for storing water.
No, a cricket ball cannot be used to play tennis because it is too hard, heavy and lacks the required bounce. Tennis balls are lighter, softer and specifically designed to suit the game’s dynamics.
Different materials are used for making sports balls to suit the specific needs of each game, such as durability, bounce, weight, and grip. These factors influence the ball’s performance and player control in different environments.
No, not all lustrous materials are metals. While metals like gold and silver are lustrous, non-metals like diamonds and certain minerals also exhibit luster. Luster is not exclusive to metals but depends on surface properties.
