## Science / Motion and Time

### Science / Motion and Time

Motion makes the world go 'round'. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. But motion is so much more.

A body is said to be in motion if it changes its position with respect to fixed point or objects around it.

Explore the different types of motions in your daily life:

• Oscillatory motion - motion of swing
• Rectilinear motion - motion of car on straight road
• Rotational motion - motion of merry-go-round

Calculate the speed of an object by finding out the distance covered by the object in unit time. Also compare which object is moving faster.
Learn about simple pendulum and methods to find its time period.
Motion of objects can be presented in pictorial form by their distance-time graphs. Learn to draw different distance-time graphs for uniform motion and non-uniform motion.

### Factoids

Galileo was sitting in a church. He noticed that a lamp suspended from the ceiling with a chain was moving slowly from one side to the other. He was surprised to find that his pulse beat the same number of times during the interval in which the lamp completed one oscillation. This observation led to the development of pendulum clocks.
