Answer:
1.A force acting on a object causes the object to change it's shape or size, to start moving,to stop moving,to accelerate or decelerate.When there's the interaction between two objects they exert a force on each other,these exerted forces are equal in size but opposite in direction.
2.When we press the foam,it's shape is changed.When we stretch the rubber bend,then it's shape is changed.Making of bread from dough.Squeezing an orange and cause a change in it's size.Similar is the result with compressing a clay ball.
Target competency:When force is applied on a stationary object,the object tends to move in the direction in which force is applied,for example,applying force on a stationary tennis ball will make it continue it's motion in the direction of applied force.
