Question

A football was in the same position in a football ground for 10 minutes but as soon as Rajat kicks the ball, it starts to move in a straight line. Which of the following options correctly explains the initial and final states of the football?

• A.
  • Initial state: Rest
  • Final state: Circular motion
• B.
  • Initial state: Linear motion
  • Final state: Rest
• C.
  • Initial state: Rest
  • Final state: Linear motion
• D.
  • Initial state: Circular motion
  • Final state: Rest

Answer 1

The correct option is C

• Initial state: Rest
• Final state: Linear motion

When the object does not change its position with respect to time, it is known to be at rest.

When the body moves in a straight line with respect to time, the motion is called linear motion.

Initially, the ball was at rest but as soon as Rajat kicks the ball it starts to move in a straight line path (linear motion).

Moreover, if the body moves in a circular path then it is said to be in circular motion but the ball here depicts the linear motion.
