Question

state the effect of force of the following cases.. a)streching a rubber band. b)kicking a football....​

Answer 1

Explanation:

A) Rubbery materials act like simple springs when they're not deformed too much. Following the relation known as Hooke's law, a 10 percent increase in stretching force will make a typical rubber band 10 percent longer.

B) while taking a penalty kick in football, the player applies a force on the ball. Before being hit, the ball was at rest and so its speed was zero. The applied force makes the ball move towards the goal. ... If the force applied on the object is in the direction of its motion, the speed of the object increases.
