Answer. (i) The motion of a body in a straight line is called rectilinear or linear motion. Example — A car moving on a straight road. (ii) If the motion of a body is along a curved path, it is said to be a curvilinear motion. Example — The motion of a cycle while taking a turn on the road.
False. 2. Fill in the blanks. Two boys cycling on the road with the same speed are at rest. The motion in a straight line is rectilinear motion. One to and fro motion of a clock pendulum takes time = 2 s. 36 km h-1 = 10 m s-1. Total distance travelled = average speed × total time taken. The weight of a girl is 36 kgf.

We can define motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc., all exhibit motion. Even the air that we breathe exhibits motion! Everything in the universe moves. We live in a universe that is in continual motion. The fundamental particle of matter, t...
We might have noticed that different objects move differently. Some objects move in a curved path, some in a straight path and a few others in a different way. According to the nature of the movement, motion is classified into three types as follows: 1. Linear Motion 2. Rotary Motion 3. Oscillatory Motion
Now let us understand motion clearly with the help of a few examples. 1. Our daily activities, like walking, running, closing the door, etc. involve motion. There is a change of position of the object involved in these activities. 2. The flow of air in and out of our lungs is also an example of motion. 3. The automobiles that carry passengers from ...

2. Circular motion: When a body moves in the shape of a circle about a fixed point and a fixed radius, then the body is said to be in a circular motion. For example, the motion of planets around the sun. 3. Period / Oscillatory motion: When the motion of a body repeats after fixed intervals of time, then the body is said to be in the periodic ...

[BL] Have students practice describing simple examples of motion in the class from different reference frames. For example, slide a book across a desk. For example, slide a book across a desk. Ask students to describe its motion from their reference point, from the book's reference point, and from another student's reference point.
learning objectives. Define kinematics. Kinematics is the branch of classical mechanics that describes the motion of points, objects and systems of groups of objects, without reference to the causes of motion (i.e., forces ). The study of kinematics is often referred to as the “geometry of motion.”. Objects are in motion all around us.
