Question

identify the type of motion in each of the following
a) falling of an apple from tree
b) the Earth revolving around the sun
c) a coin moving over a carrom board
d) the motion of a pendulum of clock
e) a ball thrown upward at and angle​

Answer 1

Explanation:

In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.There are different types of motion: translational, rotational, periodic, and non periodic motion.

Answer 2

Answer:

1. Legend has it that a young Isaac Newton was sitting under an apple tree when he was bonked on the head by a falling piece of fruit, a 17th-century “aha moment” that prompted him to suddenly come up with his law of gravity.
2. The motion of the earth around the sun in its orbit is known as revolution. The earth takes 365.26 days to complete one revolution. The different seasons we experience in a year is a result of this revolution.
3. carrom board coin moves in a straight line between two collision thus the motion followed by coin is rectilinear motion.
4. The pendulum of a 'pendulum clock' is a long metal rod having a heavy metal bob at its lower end. When the lower end of pendulum is displaced to one side and then released, the pendulum starts swinging left and right continuously. The pendulum clock uses this periodic motion of pendulum for measuring time
5. A ball is thrown upward at an angle of 30∘ with the horizontal and lands on the top edge of a building that is 20m away. The top edge is 5m above the throwing point. The initial speed of the ball in metre/second is (take g = 10 m/s2)
