[amp_mcq option1=”Force” option2=”Torque” option3=”Linear momentum” option4=”Impulse” correct=”option2″]<\/p>\n
The correct answer is: B. Torque<\/p>\n
Torque is the rotational equivalent of force. It is a vector quantity that is defined as the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation. Torque is the only quantity that can cause a change in angular momentum.<\/p>\n
Linear momentum is the product of mass and velocity. It is a vector quantity that is defined as the product of the mass of an object and its velocity. Linear momentum is conserved, which means that the total linear momentum of a system remains constant unless an external force acts on the system.<\/p>\n
Impulse is the product of force and time. It is a vector quantity that is defined as the product of the force acting on an object and the time during which the force acts. Impulse is used to calculate the change in momentum of an object.<\/p>\n
The rate of change of angular momentum is equal to torque. This is because torque is the only quantity that can cause a change in angular momentum.<\/p>\n","protected":false},"excerpt":{"rendered":"
