Question

Which of the following types of motion are possessed by a football rolling on the ground? i) Rotational Motion ii) Circular Motion iii) Rectilinear Motion iv) Periodic Motion a) i and ii b) ii and iii c) i and iii d) ii and iv

Answer 1

Answer:

Rectilinear and Rotational motion is the right answer.

Hope it helpfull

Answer 2

A rolling football on ground possess c) i and iii which means rotational motion and rectilinear motion.

Explanation:

• A rolling ball undergoes rotational motion and rectilinear motion.

• Rotational motion is in the rolling of the ball and rectilinear motion helps in letting the ball move forward.

Rotational Motion

• The motion of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity.

• The rotation of a particle about a fixed point in space.

Examples of rotational motion: Rotation of earth about its axis.

Rectilinear motion

• An object is said to be in rectilinear motion if any two points of the body cover an equal distance along two separate parallel lines, in a fixed amount of time.

• A linear propagation of an object in one dimension, along a straight line path is known as rectilinear motion.

Examples of rectilinear motion: Motion of elevator in a building.
