Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Choose the terms that complete the paragraph. In this lab, you used the characteristics for classifying minerals and rocks to identify mineral and rock samples. To identify the relative hardness of minerals, you conducted a
test. To determine the color of the powder of a mineral, you conducted a

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
