Physics It is easier to roll a barrel full of coal tar than to pull it because the full weight of the barrel comes into play when it is pulled the rolling friction is much less than the sliding friction coal tar is a liquid and it flows in the barrel when it is rolled more surface area of the barrel is in contact with the road when it is pulled the full weight of the barrel comes into play when it is pulled the rolling friction is much less than the sliding friction coal tar is a liquid and it flows in the barrel when it is rolled more surface area of the barrel is in contact with the road when it is pulled ANSWER DOWNLOAD EXAMIANS APP
