O It is possible to use quantity methods using scalars. A scalar quantity may either be positive or negative. A vector quantity may either be positive or negative. Two vectors can be added only if they have direction.Which among the following situations results to greatest momentum? A more massive object moving fast O A less massive object moving slowly O A more massive object moving slowly O A less massive object moving fastWhich of the following statements is TRUE about tension force? O The sum of the horizontal component of all strings is equal to the weight of a suspended mass assuming that the object is not moving. The vector sum of all the components of all strings minus the sum of its vertical component is equal to the weight of a suspended mass, assuming that the object is not moving. The vector sum of all the components of all strings is equal to the weight of a suspended mass, assuming that the object is not moving. The sum of the vertical component of all strings is equal to the weight of a suspended mass. assuming that the object is not moving
