Question

3. Mention the type of
motion in each of the
following:
(i) A ball moving vertically
upward.
(ii) A child moving down a
slide.
(iii) Movement of a player
in a football ground.
(iv) The flight of a butterfly.
(v) An athlete running in a
circular track.
(vi) The motion of a wheel
(vii) The motion of a cradle.​

Answer 1

Answer:

Explanation:

1. A ball moving vertically upwards : This is an example of accelerated linear motion in which the ball travels along a straight line and gravity acts in a direction opposite to that of displacement. 2. ... The child follows accelerated linear motion.
2. A child moving down a slide: A slide can be considered as an inclined plane. The child follows accelerated linear motion. Here a component of the the weight vector moves the child along a straight line on the inclined plane.
3. 3. Movement of player in football ground:A footballer follows accelerated non linear motion while playing in a football ground because he moves haphazardly and his velocity vector changes very often
4. Random motion is seen in a flying butterfly. Random motion is a motion in which the direction and speed of a particle changes continuously. ... It means the particle can go in any direction.
5. he type of motion possessed by an athlete running on a circular track is 'Accelerated Motion'. ▶️As when a body is moving along a circular path or track it, we know it constantly changes its direction, which in turn, changes the velocity as it is a vector quantity and when velocity changes there is acceleration.
6. The wheel provides basic examples of translational and rotational motion
7. the motion of a cradle is oscilatory motion based on pendulum
